- fileThe filename to read.
C++ Type:MeshFileName
Description:The filename to read.
FileMeshGenerator
Support File Formats
The FileMeshGenerator is the default type for MOOSE and as the name suggests it reads the mesh from an external file. MOOSE supports reading and writing a large number of formats and could be extended to read more.
| Extension | Description |
|---|---|
| .e, .exd | Sandia's ExodusII format |
| .dat | Tecplot ASCII file |
| .fro | ACDL's surface triangulation file |
| .gmv | LANL's GMV (General Mesh Viewer) format |
| .mat | Matlab triangular ASCII file (read only) |
| .msh | GMSH ASCII file |
| .n, .nem | Sandia's Nemesis format |
| .plt | Tecplot binary file (write only) |
| .node, .ele; .poly | TetGen ASCII file (read; write) |
| .inp | Abaqus .inp format (read only) |
| .ucd | AVS's ASCII UCD format |
| .unv | I-deas Universal format |
| .xda, .xdr | libMesh formats |
| .vtk, .pvtu | Visualization Toolkit |
