vsbv

Mapdl.vsbv(nv1='', nv2='', sepo='', keep1='', keep2='', **kwargs)

Subtracts volumes from volumes.

APDL Command: VSBV

Parameters:

nv1

Volume (or volumes, if picking is used) to be subtracted from. If ALL, use all selected volumes. Volumes specified in set NV2 are removed from set NV1. If P, graphical picking is enabled (valid only in the GUI) and remaining fields are ignored. A component name may also be substituted for NV1.

nv2

Volume (or volumes, if picking is used) to subtract. If ALL, use all selected volumes (except those included in the NV1 argument). A component name may also be substituted for NV2.

sepo

Behavior if the intersection of the NV1 volumes and the NV2 volumes is an area or areas:

(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.

keep1

Specifies whether NV1 volumes are to be deleted:

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

DELETE - Delete NV1 volumes after VSBV operation (override

BOPTN command settings).

KEEP - Keep NV1 volumes after VSBV operation (override

BOPTN command settings).

keep2

Specifies whether NV2 volumes are to be deleted:

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

DELETE - Delete NV2 volumes after VSBV operation (override

BOPTN command settings).

KEEP - Keep NV2 volumes after VSBV operation (override

BOPTN command settings).

Notes

Generates new volumes by subtracting the regions common to both NV1 and NV2 volumes (the intersection) from the NV1 volumes. The intersection can be a volume(s) or area(s). If the intersection is an area and SEPO is blank, the NV1 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, NV1 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. VSBV,ALL,ALL will have no effect because all the volumes in set NV1will have been moved to set NV2.
