vsba

Mapdl.vsba(nv='', na='', sepo='', keepv='', keepa='', **kwargs)

Subtracts areas from volumes.

APDL Command: VSBA

Parameters:

nv

Volume (or volumes, if picking is used) to be subtracted from. If ALL, use all selected volumes. If P, graphical picking is enabled (valid only in the GUI) and remaining fields are ignored. A component name may also be substituted for NV.

na

Area (or areas, if picking is used) to subtract. If ALL, use all selected areas. A component name may also be substituted for NA.

sepo

Behavior of the touching boundary:

(blank) - The resulting volumes will share area(s) where they touch.

SEPO - The resulting volumes will have separate, but coincident area(s) where they

touch.

keepv

Specifies whether NV volumes are to be deleted:

(blank) - Use the setting of KEEP on the BOPTN command.

DELETE - Delete NV volumes after VSBA operation (override BOPTN command settings).

KEEP - Keep NV volumes after VSBA operation (override BOPTN command settings).

keepa

Specifies whether NA areas are to be deleted:

(blank) - Use the setting of KEEP on the BOPTN command.

DELETE - Delete NA areas after VSBA operation (override BOPTN command settings).

KEEP - Keep NA areas after VSBA operation (override BOPTN command settings).

Notes

Generates new volumes by subtracting the regions common to both the volumes and areas (the intersection) from the NV volumes. The intersection will be an area(s). If SEPO is blank, the volume is divided at the area and the resulting volumes will be connected, sharing a common area where they touch. If SEPO is set to SEPO, the volume is divided into two unconnected volumes with separate areas where they touch. See the Modeling and Meshing Guide for an illustration. See the BOPTN command for an explanation of the options available to Boolean operations. Element attributes and solid model boundary conditions assigned to the original entities will not be transferred to the new entities generated.
