Import surface mesh from Gmsh 2.6.1

[hkroeger]

Hello,

recently I got problems during import of gmsh surface meshes, created with latest version of gmsh. I guess this might be due to changes in the gmsh format.

For my case, the gmsh header contained an additional section between the keywords "$EndMeshFormat" and "$Nodes" with the patch names, which irritated engrid.
The current header looked like this:
$MeshFormat
2.2 0 8
$EndMeshFormat
$PhysicalNames
10
2 1 "rotor_upstream"
...
3 10 "blade"
$EndPhysicalNames
$Nodes
34428
...
.

To handle this, e.g. the following change around line 134 in gmshreader.cpp might be useful:

    /*
    f >> word;
    if (word != "$Nodes") EG_ERR_RETURN("$Nodes expected");
    */
    while (word != "$Nodes")
    {
        f >> word;
        if (f.status() != QTextStream::Ok) EG_ERR_RETURN("$Nodes expected");
    }
