Hi,

I just tried to build meshkit, with the following configure:

./configure --enable-debug --with-itaps=/mnt/disk2b/jhu/ddriv

it failed on compiling EdgeMesher make[3]: Entering directory `/mnt/disk2b/jhu/meshkit/algs' CXX EdgeMesher.lo In file included from EdgeMesher.cpp:1: EdgeMesher.hpp:16:18: error: iRel.h: No such file or directory In file included from EdgeMesher.cpp:1: EdgeMesher.hpp:40: error: ‘iRel_Instance’ has not been declared EdgeMesher.hpp:40: error: ‘iRel_PairHandle’ has not been declared In file included from EdgeMesher.cpp:1: EdgeMesher.hpp:57: error: ‘iRel_Instance’ does not name a type EdgeMesher.hpp:58: error: ‘iRel_PairHandle’ does not name a type EdgeMesher.cpp:5: error: ‘iRel_Instance’ has not been declared EdgeMesher.cpp:5: error: ‘iRel_PairHandle’ has not been declared EdgeMesher.cpp: In constructor ‘EdgeMesher::EdgeMesher(iGeom_Instance_Private*&, iBase_EntityHandle_Private**, iMesh_Instance_Private*&, int&, int*)’: EdgeMesher.cpp:31: error: ‘assoc’ was not declared in this scope EdgeMesher.cpp:32: error: ‘rel’ was not declared in this scope EdgeMesher.cpp: In member function ‘void EdgeMesher::EdgeMesh()’: EdgeMesher.cpp:120: warning: unused variable ‘NumEntitySet’ EdgeMesher.cpp: In member function ‘std::vector<double, std::allocator<double> > EdgeMesher::BiasMeshing()’: EdgeMesher.cpp:203: warning: unused variable ‘err’ EdgeMesher.cpp:204: warning: unused variable ‘x’ EdgeMesher.cpp:204: warning: unused variable ‘y’ EdgeMesher.cpp:204: warning: unused variable ‘z’ EdgeMesher.cpp:204: warning: unused variable ‘du’ EdgeMesher.cpp: In member function ‘std::vector<double, std::allocator<double> > EdgeMesher::DualBiasMeshing()’: EdgeMesher.cpp:250: warning: unused variable ‘err’ EdgeMesher.cpp:251: warning: unused variable ‘x’ EdgeMesher.cpp:251: warning: unused variable ‘y’ EdgeMesher.cpp:251: warning: unused variable ‘z’ EdgeMesher.cpp:251: warning: unused variable ‘ustart’ EdgeMesher.cpp:251: warning: unused variable ‘du’ EdgeMesher.cpp: In member function ‘void EdgeMesher::RapidSorting(std::vector<double, std::allocator<double>

I've updated cgm, moab and meshkit, and built, installed cgm and moab, did I left something out?

Thanks.

In my case of using OCC geometry, attribute updating and removing time take too long. It takes more than import/exporting time of the geometry.

Thank you for providing the testcase. OCC did have a reputation of getting much slower with larger models and more operations. I'll have a look on Monday to see if there's anything I can do on cgm side that can speed it up.

Have a nice weekend!

When subtracting 325 pins from a block, OCC takes a lot more time than the corresponding ACIS model. I'm attaching the assygen .inp that can be run as MeshKit/rgg>assygen 7. This file is for OCC version of MeshKit. For ACIS change the geometry engine to ACIS in the .inp file and run ACIS version.

RGG o/p:

ACIS:

Normal Termination. Geometry file: 7.sat saved. Schemes file created: 7.template.jou Cubit journal file created: 7.jou Ending at : Fri Feb 25 15:10:31 2011 Elapsed wall clock time: 8 seconds or 0.133333 mins

OCC:

Exported: 327 OCC Bodies to 7.stp

Normal Termination. Geometry file: 7.stp saved. Schemes file created: 7.template.jou Cubit journal file created: 7.jou Ending at : Fri Feb 25 14:59:51 2011 Elapsed wall clock time: 3173 seconds or 52.8833 mins

The geometry files can be found at /homes/jain/MeshKit-all/trunk/rgg/test/geometry_parallel_meshing/7.stp and 7.sat
