Dear MeshKit users, The consolidated release of SIGMA v1.3 is available now, and contains the MeshKit 1.5.0 major release candidate. The release tarball can be downloaded at: ftp://ftp.mcs.anl.gov/pub/fathom/meshkit-1.5.0.tar.gz. We would also like to thank our users and contributors for making this release possible. The notable changes in MeshKit v1.5.0 are: * Added a parallel triangle advancing front algorithm for surface meshing; Also added support for fully open-source NetGen tetrahedral meshes, uses MeshKit-AdvFront triangle meshing underneath * Netgen can be auto downloaded during configuration (if not available on the user system) * Mesquite support is now enabled directly via MOAB. i.e., configure MOAB with --enable-mesquite option and build with MeshKit to enable Mesquite support * Remove .sat/ACIS files creation support due to interface/capability change in CGM (refer to CGM release notes) * Added a new MKmesh tool for invoking any available meshing algorithm on a geometry * Support for facet based geometry (default in CGM) for several algorithms * Considerable updates to the autotools build system, and introducing a new CMake based build system with test and tools; Several dependencies are currently not handled with CMake but this will be added in an upcoming minor release. * RGG support for Trelis using configure option --enable-rgg16 option Please refer to the following link to find all changes in the SIGMA components and more specifically, information about the fixes and enhancements in CGM as part of this release. http://sigma.mcs.anl.gov/news/sigma-release-1-3/ Let us know if you have any questions or encounter any issues during your upgrade. Best, The SIGMA team

The consolidated release of SIGMA v1.2.1 is available now that contains the MeshKit 1.4.1 release candidate. The release tarball can be downloaded at: ftp://ftp.mcs.anl.gov/pub/fathom/meshkit-1.4.1.tar.gz. The notable changes in MeshKit v1.4.1 are: * Added support for HEX27 element creation in CoreGen mesh generation, through specifications in the input file. * New keyword 'MESHTOGEOM' supported for CUBIT mesh files. A new tool *mbmeshtogeom* has been added in MOAB to compute MESHTOGEOM ratio on an already existing mesh file. * Improved CoreGen parallel save time by optionally allows users to specify the sets that need to be saved (e.g., save only Material, Neumann and Parallel partition sets). * Compute timing summary for CGM boolean operations during mesh generation. * Improved support for Kitware's CMB and RGG tools Please refer to the following link to find all changes in the SIGMA components and more specifically,. information about the fixes and enhancements in MeshKit as part of this release. http://sigma.mcs.anl.gov/news/sigma-v1-2-1 Let us know if you have any questions or encounter any issues during your upgrade.

Dear users, The consolidated release of SIGMA v1.2 is available now that contains the MeshKit 1.4.0 release candidate. The release tarball can be downloaded at: ftp://ftp.mcs.anl.gov/pub/fathom/meshkit-1.4.0.tar.gz. The notable changes in MeshKit v1.4.0 are: * Updated support to use geometry representations with CGM 15.0 and use Cubit 14.9/15.0 for mesh generation * Old MeshKit/algs, MeshKit/utils and MeshKit/rgg are deleted. RGG tools CoreGen and AssyGen are fully functional and adhere to the graph-based scheme. * A new MeshOp (FacetMeshReader) has been added * Lasso has been removed as a dependency. MOAB must now be configured --with-irel option for building MeshKit. * AssyMesher: A new MeshOp for meshing OCC (.brep) type reactor assembly meshes generated has been added. * Improved support for Kitware's CMB and RGG tools Please refer to the following link to find all changes in the SIGMA components and more specifically,. information about the fixes and enhancements in MeshKit as part of this release. http://sigma.mcs.anl.gov/news/sigma-release-1-2/ Let us know if you have any questions or encounter any issues during your upgrade.

Ask for help about using the MeshKit
by Tang Laoya 18 Oct '13

Dear developer, I am a student in China and I am studying the algorithm of quadrilateral mesh generation. I was required to develop the software to generate quadrilateral mesh for any 2-D input domains. I am very exciting to get to know that you have very powerful open source mesh generator MeshKit. I am very interesting to the quadrilateral mesh generate part. From your document, I got to know that the 'JaalQuad<http://ftp.mcs.anl.gov/pub/fathom/meshkit-docs/html/algorithm_jaalquad.html>‘ algorithm is very suitable to me. However, I also noticed that it is required to install some dependencies and I have to build them from Linux system. My question is: If I only use the quadrilateral mesh generation module, what's the simplest way to build the tool? Is it possible to port the code to Windows system? I noticed that you said that 'On windows, try running cmake (though this is only indirectly supported, meaning it may not be up to date)' from here: https://trac.mcs.anl.gov/projects/fathom/wiki/BuildingMeshKit Could you please tell me how to build it by CMake? I only know that we should provide CMakeLists.txt to CMake, is there any other method? Thanks, Tang Laoya

Moving MeshKit repository
by Robert Smith 06 Jan '10

06 Jan '10

Hi, We'd like to move the MeshKit repository from its current location under the ITAPS repository to another location. During this move the repository will be locked down and no checkouts or updates can be made. This move should not take very long. After the move I will send out instructions on how to point your local copies to the new repository location. Please let me know now if there is any problem with moving this repository in the next day or two. I will send out another email before the repository is locked. Thanks, Bob Smith
