PETSc/MOAB/mbpart
by Gerd Heber 27 Mar '15

27 Mar '15

I use MOAB with PETSc (and DMMoab) and build it as PETSc external package (via '--download-moab=1'). This works fine, however, not all MOAB tools are built in the process. Unfortunately, the Zoltan external package is broken and as a result mbpart is not being built. Could someone clarify the Zoltan dependence of mbpart and if there's a way to build it with just Parmetis? Thanks for your help. G.

Problem with Gmsh format 2.2

Hello, i try to read a msh file (format 2.2). I come into troubles with the PhysicalNames tag. So I modified the ReadGmsh.cpp:124 if (version != 2.0 && version != 2.1 && version != 2.2) { MB_SET_ERR(MB_FILE_DOES_NOT_EXIST, filename << ": unknown format version: " << version); return MB_FILE_DOES_NOT_EXIST; } int file_format; if (!tokens.get_integers(1, &file_format) || !tokens.get_integers(1, &data_size) || !tokens.match_token("$EndMeshFormat")) return MB_FILE_WRITE_ERROR; // If physical entities in the gmsh file -> discard this const char* const phys_tokens[] = {"$Nodes", "$PhysicalNames", 0}; int hasPhys = tokens.match_token( phys_tokens ); if (hasPhys == 2) { long num_phys; if (!tokens.get_long_ints(1, &num_phys)) return MB_FILE_WRITE_ERROR; for (int loop_phys=0; loop_phys<num_phys; loop_phys++) { long physDim; long physGroupNum; char const * physName; if (!tokens.get_long_ints(1, &physDim)) return MB_FILE_WRITE_ERROR; if (!tokens.get_long_ints(1, &physGroupNum)) return MB_FILE_WRITE_ERROR; if (!tokens.get_string()) return MB_FILE_WRITE_ERROR; } if ( !tokens.match_token("$EndPhysicalNames") || !tokens.match_token("$Nodes") ) return MB_FILE_WRITE_ERROR; } } Maybe this is of intereset for other users. In this case the reader just ignores all physicalNames if present.

CS&E 2015

All, Most of the SIGMA team developers will be attending the CS&E 2015 conference at Salt Lake city [1] from Mar 14-18, presenting some of our recent work in various sessions. We also have a poster in the CS&E Software Minisymposterium [2] with a demo table (!), which should be a fun and informal way to talk to us in person. If you have any particular work that you would like to showcase, please send me a description and a link to images/videos that we can add to our demo videos (hopefully before Tuesday). We are also consolidating all recent publications using SIGMA tools and so we would appreciate if you can send pointers to those too. Hope to see many of you at Salt Lake next week. Best, Vijay [1] http://www.siam.org/meetings/cse15/ [2] http://meetings.siam.org/sess/dsp_programsess.cfm?SESSIONCODE=20418
