Abaqus/CAE: Define nodal coordinate systems for prescribed conditions in the Load module.

Reference:

Required parameter:

NSET

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

Optional parameter:

TYPE

Set TYPE=R (default) to indicate a rectangular Cartesian system (Figure 19.11–1). Set TYPE=C to indicate a cylindrical system (Figure 19.11–2). Set TYPE=S to indicate a spherical system (Figure 19.11–3).

Data line to define a transformed coordinate system: 

First (and only) line:

  1. Global X-coordinate of point a specifying transformation.

  2. Global Y-coordinate of point a specifying transformation.

  3. Global Z-coordinate of point a specifying transformation.

  4. Global X-coordinate of point b specifying transformation.

  5. Global Y-coordinate of point b specifying transformation.

  6. Global Z-coordinate of point b specifying transformation.
