Hi Florent, The doxygen documentation pages [1] and the website [2] provide some information depending on what you want to do. We currently do not have any examples in CGM and are planning to add few in the coming months. For mesh generation, I suggest you please take a look at MeshKit, which uses CGM and MOAB underneath to handle the geometry and mesh queries, while optionally interfacing with external tools such as Cubit to generate high-quality meshes. What is the general complexity in your geometry and what kind of meshes do you want to generate (HEX, TET. Hybrid) ? Also if you have any specific questions about the usage, do let us know.

Hello, CGM alone would not be enough to generate a mesh CGM is mostly a wrapper around other geometry kernels, ACIS or OCC/OCE based. To generate a mesh you would need the SIGMA stack. http://sigma.mcs.anl.gov/ I am not familiar with what format you need your mesh for EFISPEC3D; I assume it is similar to NEK5000 solver, which is a spectral element method too. (so Nek needs a hexahedral mesh) And what is the input geometry format? Terrain data? We have some capabilities developed for ice sheet modeling. At the core, they do need a quadrilateral mesher for surfaces, which are then extruded/swept to form hexahedral elements. Also, it is assumed that the domain of interest does not have internal caves/tunnels, so the sweeping in vertical direction is trivial. I am not sure how these would help your project.

Build failed in Jenkins: cgm_par #969
by jenkins-ci＠mcs.anl.gov 15 Nov '15

15 Nov '15

See <https://jenkins-ci.mcs.anl.gov/job/cgm_par/969/changes> Changes: [iulian] test edge orient was not reporting correctly [wuda] Updated CGM version to 14.9 [wuda] Added a small test case to export a body (cylinder) to an ACIS SAT file. [wuda] These header files are exactly the same in CGMA14.0 and CGMSandia14.0, so we can safely replace them with CGMSandia14.9 versions. [wuda] These header files are different in CGMA14.0 and CGMSandia14.0, so we should manually merge them with CGMSandia14.9 versions. [wuda] Added some new header files from CGMSandia14.9 [wuda] Fixed all build errors caused by updated header files. [wuda] A workaround (register attribute 43 as a dummy one) for make check to pass. [wuda] MOAB with this version of CGM needs some new header files installed. [wuda] Disable specific warnings: anonymous variadic macros were introduced in C99 [-Wvariadic-macros] [wuda] itaps test executables are not linking on cubit 14.9 (this is only in shared mode, fixed by Iulian Grindeanu). [wuda] For the time being, register dummy attribute type 43 for OCC-based CGM as well. [wuda] DLIListSorter prevents classes using DLIList from being sorted by pointer. However, in OCCCurve::get_interior_extrema(), DLIList<CubitVector*> point_list needs to be sorted. Comment out DLIListSorter in DLIList::sort() for the time being. [wuda] These header files are exactly the same in CGMA14.0 and CGMSandia14.0, so we can safely replace them with CGMSandia14.9 versions. [wuda] These source files are exactly the same in CGMA14.0 and CGMSandia14.0, so we can safely replace them with CGMSandia14.9 versions. [wuda] These header files are exactly the same in CGMA14.0 and CGMSandia14.0, so we can safely replace them with CGMSandia14.9 versions. [wuda] These header files are different in CGMA14.0 and CGMSandia14.0, so we should manually merge them with CGMSandia14.9 versions. [wuda] These source files are different in CGMA14.0 and CGMSandia14.0, so we should manually merge them with CGMSandia14.9 versions. [wuda] Fix build errors from some .hpp and .cpp files under geom/OCC/ [wuda] Added some new header files and source files from CGMSandia14.9. Some of them are actually not new: FacetProjectTool.*pp and PST_Data.*pp are moved from geom/virtual to geom/facet. CCbuitFile.cpp is exactly the same as the original CubitFile.cpp (Note: GMSandia14.9 has totally rewritten CubitFile.cpp for another new class). [wuda] Deleted some files that are no longer in CGMSandia14.9 [wuda] Updated some Makefiles for deleted and added files. [wuda] Fixed an error in geom/facet/Makefile.am [wuda] Fix build errors from test/modify.cpp [wuda] Fix more build errors from OCC unit tests. [wuda] Manually merge a few more files to have both CGMA14.0 and CGMSandia14.9 changes. [wuda] BasicTopologyEntity has a static_cast from CGMSandia14.9 changing that back to dynamic_cast. [wuda] Adding step file for make distcheck to work [wuda] Remove from CMakeLists.txt files that are not there. [wuda] cmake build fixes [wuda] remove missing files from CMakeLists.txt [wuda] Change WIN32 to _WIN32 for some files copied from CGMSandia14.9 [iulian] missing file from installation [iulian] prepare for cgm 15.0 release [iulian] version 15.0 [iulian] add to distribution mesh files [wuda] Fix some compiler warnings during make and make check. [wuda] Fix some errors during make distcheck. [wuda] Fix some compiler warnings from two CGM header files when building MOAB: declaration of ‘end’ shadows a member of 'this', unused parameter 'face', unused parameter 'loop_list'.

In review of the pull request I created, it came up that the read_cgm_senses_test of MOAB was broken by this change. I have pushed an updated version of that test to a vanderzee/faceVolSense branch of the MOAB repository. With that change, my local build of moab-oce passes all of the tests in make check. This particular test has hard-coded what face-to-volume and edge-to-face senses it expects to get when it reads MeshFiles/unittest/io/cylcube.stp file. The geometry contains two volumes, a cube and a cylinder, that do not touch or overlap. Since my changes to CGM now produce normal vectors and face-to-volume senses that are in accordance with what is stored in the .stp file rather than always producing a forward sense on all faces and not having the sense in accordance with the normal vector, and since some of the faces in the .stp file have reversed sense, the face-to-volume and edge-to-face senses that this test expects needed to be changed. In the attached spreadsheet – which I think will open in OpenOffice if you don’t have Excel – I describe the changes I’ve made in a way that’s probably a bit easier to understand than the code. I have an initial table that shows how all 10 faces expected a forward (F) sense, but now half of them expect a reverse (R) sense. In the lower table I list the edge-to-face senses. Here the expectation is that wherever the sense of a face has changed to the reverse sense, the sense of the edge with respect to that face should flip. You should be able to see how my changes respect that. Also, the order in which the edges are read changed slightly, so edges 6 and 8 swapped IDs. I also made some changes to the check_sense_data method of the test so that the test does not depend on having the known senses and the senses read from the file in the same order. This seemed to be the intent of that method, but was not behaving that way. If the test is supposed to depend on reading things in the same order, you can revert the two lines I added to that method, and the test will still pass. Finally, I changed the test to check the face-to-volume senses before it checks the edge-to-face senses, because the expectation one has for edge-to-face sense depends on the face-to-volume sense. That reflects a preference that I have, but again, is not at all essential. -Evan From: jain(a)mcs.anl.gov [mailto:[email protected]] Sent: Wednesday, August 26, 2015 4:50 PM To: Vander Zee, Evan B.; cgma-dev(a)mcs.anl.gov Subject: Re: [cgma-dev] cgma-dev Digest, Vol 81, Issue 3 Yes, create a PR.

Should I create a pull request for this branch? At this point I do not follow the convention of having surfaces oriented to return outward-facing normals if there is only one volume. Instead, I updated the code so that if you ask for the face-to-volume sense, then you will get the proper answer – forward if the normal faces outward and reversed if the normal faces inward. Moreover, the facets that are returned from get_graphics agree with the normal vector, i.e., they are oriented to be counterclockwise if you were looking down at the surface from the direction that the normal points toward. In other words, the triangle normal computed by the cross product of v1 – v0 with v2 – v0 would point in the same direction as the surface normal. I think this works in most situations, but I suspect that there are some corner cases that I do not know enough about where this would fail. In particular, I am concerned that merge, imprint, or other cases that make essential use of the bridge_sense may fail. Please let me know if you run across a case where what I’ve described is not the case. If we require support for getting all of the triangles returned from get_graphics to be counterclockwise with respect to normals facing outward from a particular volume, then let’s discuss what an appropriate API would be for supporting that use case. It should be quite easy to implement something like that now, but in my opinion the API would have to include specifying the volume from which you want the triangle normal vectors to face outward. -Evan From: cgma-dev-bounces(a)mcs.anl.gov<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Vander Zee, Evan B.

My original diagnosis was incorrect. Here’s what the problem was. For the Cubit-generated bricks I was not traversing the edges in the expected order, so after I set up all of the edge senses properly, some later code was reversing all of the edge senses for the Cubit-generated files. When I changed the code to traverse the edges in the expected order, I pass my modified test_edge_orient for brick_2.stp as well as for a box created inside of CGM and when reading the file that contains the box created inside of CGM. After the latest code change, a new test is failing. This is the point_project test. The way the test is written, it projects a point onto a surface using the closest_point_trimmed method. There are two edges that the point could project onto that are equally close. In the current CGM/OCC implementation, the edge that is chosen depends on the internal ordering of the edges, so it makes sense that my code changes could have flipped the test to choose the other of the two equally close edges. I don’t see any documentation saying that the tie should be broken in a particular fashion, so I plan to change the test to allow projecting the point to either of the equally close edges. Thanks for your help. You should see some commits to my vanderzee/faceVolSense branch later today after I clean up the code a bit. -Evan From: jain(a)mcs.anl.gov<mailto:[email protected]> [mailto:[email protected]] Sent: Wednesday, August 26, 2015 10:41 AM To: Vander Zee, Evan B.; cgma-dev(a)mcs.anl.gov<mailto:[email protected]> Cc: Andrew Davis Subject: Re: [cgma-dev] cgma-dev Digest, Vol 81, Issue 3 Hi Evan, I'd say get the same file from CUBIT and from OCC directly, compare, but follow and adhere to OCC and submit a patch to CUBIT to update their CGM.

The result .stp file is not the same as brick_2.stp, but it is similar. I also tried creating a brick in Cubit 13 and exporting to an .stp file. Then I tried creating a brick in Cubit 14.9 and exporting that to an .stp file. All of these have the same problem with edge orientation in the .stp file, and all of them have the same problem when I test them against my revised test_edge_orient. One way to fix the problem by editing these .stp files is to change the geometry in the .stp file so that all normal vectors in the brick face geometries point outward from the brick. The way these .stp files are written, the normal points outward from the top face of the brick, but points inward from the other five faces of the brick. I have deciphered some of the syntax for an STP file, but not all. The website that has helped me the most, I think, is the NIST website. At http://www.nist.gov/el/msid/infotest/step-file-analyzer.cfm there is a STEP analyzer that can create a spreadsheet summary of the entities that are in an STP file. From looking at some sample output of this tool that the website provided at http://www.nist.gov/el/msid/infotest/upload/STEP-File-Analyzer_stp.xlsx you can at least see the names of the attributes of some of the entities. I had also looked at a couple things on Wikipedia, including the link that Rajeev sent, but I did not find them very helpful. For example, you can see that ADVANCED_FACE is defined from (1) a name, (2) a list of bounds, (3) a face_geometry, and (4) a same_sense attribute. The same_sense attribute identifies the sense relative to any CLOSED_SHELL that the ADVANCED_FACE belongs to, if I am interpreting it correctly. In the .stp files that Cubit writes out for a brick, the bounds list for an ADVANCED_FACE happens to consists of one FACE_OUTER_BOUND, which has an attribute that is an EDGE_LOOP, and the EDGE_LOOP has an edge_list attribute that is a list of ORIENTED_EDGE. Digging down into the entites inside an "oriented edge" and the attributes it has you find that for a Cubit brick the "oriented edge" happens to be a sense together with an edge "curve" defined from two vertices and a line that passes through the two points. The line is defined by a point and a direction vector. I won't bore you with all of the specific entities involved. The key thing to notice is that ORIENTED_EDGE defines the sense of the edge relative to the loop it belongs to, i.e., relative to the face that is bounded by that loop, and the direction vector tells the parametrization of the edge that gives the edge its native orientation. The face geometry in .stp files that Cubit writes out for a brick is a PLANE, which is defined by an AXIS2_PLACEMENT_3D. The spreadsheet tells me that AXIS2_PLACEMENT_3D consists of (1) a name, (2) a location, (3) an axis, and (4) a ref_direction. Based on that and some of my reading of Open Cascade reference documention for Geom_Axis2Placement, as well as what makes sense when looking at the data, I interpret the axis to be a normal vector to the plane, and the ref_direction to be a direction vector within the plane, probably in the direction of the u parameter, though I'm not sure yet whether that matters. The axis/normal vector defines the native orientation of the plane so that we know what "counterclockwise" or "to the left of the edge" means and can interpret the same_sense attribute of the advanced face. Open Cascade clearly states that it supports STEP, as documented at the web page http://www.opencascade.org/doc/occt-6.9.0/overview/html/occt_user_guides__s…, and appears to do a good job of supporting it. We are using their STEPControl_Reader in the import_solid_model method in OCCQueryEngine.cpp to read .stp files into an OCC geometry model. The issue appears to be whether the sense in an ORIENTED_EDGE should be multiplied by the sense in an ADVANCED_FACE. In the file written by Cubit, the sense of the oriented edge is multiplied by the sense of the ADVANCED_FACE, but the way that it is being interpreted by OCC, it seems that the sense of the oriented edge should not be multiplied by the sense of the advanced face. I haven’t finished researching how OCC interprets the ADVANCED_FACE and its sense when it reads STEP format, so I suppose that there could be a disconnect there. -Evan From: Grindeanu, Iulian R.

Maybe we could import the stp file again in cubit, "regularize" or something, and export again (with cubit 14, as an stp ) will you see the same problems in your test? Evan, did you decipher the orientation issues/ syntax in an STP file? what websites did you find? standards, etc? What do OCC/OCE say about stp format? Is it fully supported? What do we do when we read stp with our OCC engine? ________________________________ From: cgma-dev-bounces(a)mcs.anl.gov<mailto:[email protected]> [cgma-dev-bounces(a)mcs.anl.gov] on behalf of Andrew Davis [andrewdavis.davis(a)gmail.com] Sent: Tuesday, August 25, 2015 12:06 PM To: cgma-dev(a)mcs.anl.gov<mailto:[email protected]> Subject: Re: [cgma-dev] cgma-dev Digest, Vol 81, Issue 3 Hi Evan My assumption would be that it was converted via Cubit from the equivalent *.sat file. Looking at git blame its from Hong-Jun Kim (stp), the sat is from Iulian. However, the stp is older than the sat by about a year Andy On Tue, Aug 25, 2015 at 12:00 PM, <cgma-dev-request(a)mcs.anl.gov<mailto:[email protected]>> wrote: Send cgma-dev mailing list submissions to cgma-dev(a)mcs.anl.gov<mailto:[email protected]> To subscribe or unsubscribe via the World Wide Web, visit https://lists.mcs.anl.gov/mailman/listinfo/cgma-dev or, via email, send a message with subject or body 'help' to cgma-dev-request(a)mcs.anl.gov<mailto:[email protected]> You can reach the person managing the list at cgma-dev-owner(a)mcs.anl.gov<mailto:[email protected]> When replying, please edit your Subject line so it is more specific than "Re: Contents of cgma-dev digest..."

CGM brick orientation test (Vander Zee, Evan B.) ---------------------------------------------------------------------- Message: 1 Date: Tue, 25 Aug 2015 16:54:28 +0000 From: "Vander Zee, Evan B." <vanderzee(a)anl.gov<mailto:[email protected]>> To: "Jain, Rajeev" <jain(a)mcs.anl.gov<mailto:[email protected]>> Cc: "cgma-dev(a)mcs.anl.gov<mailto:[email protected]>" <cgma-dev(a)mcs.anl.gov<mailto:[email protected]>> Subject: [cgma-dev] CGM brick orientation test Message-ID: <553D5F34658FB846ACEA00D6140EAC6897ADB09F(a)PAYTON.anl.gov<mailto:[email protected]>> Content-Type: text/plain; charset="us-ascii" Do you know the source of the file itaps/brick_2.stp in the CGM repository? It looks to me like the edges in the file have improper edge orientations. I have some local changes to CGM that, I thought, fix the face-to-volume sense bug. I am testing the changes in various ways and learning more about OCC and CGM. This version of itaps/brick_2.stp has been used by the test_edge_orient test in the itaps directory. I disabled the test previously in my edgeFaceSense branch when I fixed an edge-to-face orientation problem. I am working on rewriting the test now so that it properly tests the face-to-volume sense and the edge-to-face sense for both OCC and ACIS. I have the face-to-volume part of the test working fine for OCC now, but my revised edge orientation part of the test is failing. This part of the test tests edge orientation after reading the itaps/brick_2.stp file. When I create a 2 x 2 x 2 brick using iGeom_createBrick rather than reading the brick from file, my revised edge orientation part of the test passes. If I save that brick to a file, then I can also read the file I've saved, and the edge orientation part of the test passes. I looked at the brick_2.stp file and my human-readable interpretation is that the edge orientations are encoded incorrectly. I think I could correct it by hand within the file by changing the orientation of some of the oriented edges at entities 106 through 144. I want to know whether it's okay to do that or the STEP file came from some source outside of CGM that we need to be able to support. The brick that CGM writes out after iGeom_createBrick is represented quite differently from the way the one in itaps/brick_2.stp is represented. It would help me if I could get a reference for the geometric STEP entities. I have pieced together a few things through Internet searches, but I have not been able to find good reference documentation for the parts of STEP that are used by CGM. Do you know of any? -Evan vanderzee(a)anl.gov<mailto:[email protected]> ------------------------------ _______________________________________________ cgma-dev mailing list cgma-dev(a)mcs.anl.gov<mailto:[email protected]> https://lists.mcs.anl.gov/mailman/listinfo/cgma-dev End of cgma-dev Digest, Vol 81, Issue 3 ***************************************
