Which the interfaces with CAD systems are

For CAD geometries:

• IGES (input and output)
• STEP (ap 214, but ap 203 could also be work, input and output)
• VDA (input)
• DXF (input and output)
• PARASOLID [*.x_t, *.x_b] (input)
• ACIS [*.sat] (input and output)
• Rhinoceros (input and output)
• Shapefile (input)

For meshes:

• GiD format
• NASTRAN
• STL
• Vtk (in postprocess. In preprocess only Vtk voxel images are imported extracting iso-surfaces)
• Ply
• Obj
• VRML
• 3D Studio
• CGNS

Other information can be entered by the means of a batch file, and exported through a .bas template.
