### SET_GEOMETRY

###### Sets
*SET_GEOMETRY
"Optional title"
setid
gid${}_1$, ..., gid${}_8$
.
gid${}_{\mathrm{M}}$, ..., gid${}_{\mathrm{N}}$

#### Parameter definition

VariableDescription
setid Unique geometry set identification number
gid${}_1$, ..., gid${}_8$ Geometry identification number 1 to 8
gid${}_{\mathrm{M}}$, ..., gid${}_{\mathrm{N}}$ Geometry identification number M to N

#### Description

This command defines a set of geometries (see e.g. GEOMETRY_BOX).

#### Example

Pressure load on a surface defined with a geometry set

The commands below define a pressure load on square plate. Geometry 1 marks all faces on the top surface of the plate. Geometry 2 is a box. Referring to -2 means that all faces inside the box are removed from the face list. Geometry 3 adds faces inside a cylinder and, finally, Geometry 4 removes faces inside a box.
