Alexander, thanks for the modifications. We will apply this patch to the Gmsh reader and it should be available on the next minor release. Vijay On Mon, Feb 23, 2015 at 1:44 AM, Alexander Tismer <[email protected]> wrote:

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.

Best regards Alex
