*TRANSFORM

Specify a local coordinate system at nodes.

This option is used to specify a local coordinate system for displacement and rotation degrees of freedom at a node.

This page discusses:

Required parameters

NSET

Set this parameter equal to the name of the node set for which the local transformed system is being given.

Optional parameters

TYPE

Set TYPE=R (default) to indicate a rectangular Cartesian system (Figure 1). Set TYPE=C to indicate a cylindrical system (Figure 2). Set TYPE=S to indicate a spherical system (Figure 3).
