VMESH

VMESH, NV1, NV2, NINC
Generates nodes and volume elements within volumes.

PREP7: Meshing

NV1, NV2, NINC: Mesh volumes from NV1 to NV2 (defaults to NV1) in steps of NINC (defaults to 1). If NV1 = ALL, NV2 and NINC are ignored and all selected volumes (VSEL) are meshed. If NV1 = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for NV1 (NV2 and NINC are ignored).

Notes

Missing nodes required for the generated elements are created and assigned the lowest available numbers (NUMSTR). During a batch run and if elements already exist, a mesh abort will write an alternative database file (File.dbe) for possible recovery.

Tetrahedral mesh expansion (MOPT,TETEXPND,Value) is supported for both the VMESH and FVMESH commands.
