Specifies the mesh file format. Available formats are listed below.

Number

Mesh file format

-1

Disabled

0 or “none”

Automatic rectangular mesh generation or no B_integ_mesh

1 or “Ideas”

I-DEAS Universal file (extensions .unv, .ids)

2 or “ATLAS”

ATLAS file (extension .atl, or no extension)

3 or “Nastran”

Nastran file (extensions .nas, .bdf)

4 or “KSWAD”

KSWAD file (extension .ksw)

5 or “Femap”

Femap Neutral file (extension .neu)

6 or “CADAS”

CADAS file (extension .cad)

7 or “Abaqus”

Abaqus input file (extension .inp)

11 or “GMSH”

GMSH file (extension .msh)

Note: String input is case-insensitive.

Caution

Regardless of the setting above, an input mesh file (pre_geom, pre_geom2D, rotor_mesh, rotor_mesh2D, deform_mesh, deform_mesh2D, or B_integ_mesh) with no extension is recognized as ATLAS format. Other formats are recognized by their listed extensions, so add the appropriate extension to each input mesh filename.

Note

Setting value

Description

0 Default (equivalent to 1)

Ordinary FEM analysis. Uses FEM meshes in the format specified by INPUT_MESH_FILE.

1

Runs a magnetic-field calculation using only external magnetic-field sources (COIL(17.1)) or a circuit-only calculation without FEM meshes. For magnetic-field calculation using only COIL(17.1), provide a mesh for magnetic-field distribution evaluation (B_integ_mesh).

>2

For sliding-motion analysis, specifies the number of meshes for the fixed part (pre_geom(2D)) and the part with sliding motion (rotor_mesh(2D)).

Note

Description

0 Default

Runs analysis using ordinary FEM meshes.

1

Runs a magnetic-field calculation using only external magnetic-field sources (COIL(17.1)) or a circuit-only calculation without FEM meshes. For magnetic-field calculation using only COIL(17.1), provide the mesh file for magnetic-field distribution evaluation (B_integ_mesh B_INTEG(11)).
