*SYSTEM

Specify a local coordinate system in which to define nodes.

This option is used to define nodes by accepting coordinates relative to a specified local rectangular coordinate system and generating the nodal coordinates in the global coordinate system.

Data lines to define a local coordinate system

First line

  1. Xa, global X-coordinate of the origin of the local coordinate system (point a in Figure 1).

  2. Ya, global Y-coordinate of the origin of the local coordinate system.

  3. Za, global Z-coordinate of the origin of the local coordinate system.

  4. The following entries are not needed for a pure translation:

  5. Xb, global X-coordinate of a point on the X1-axis of the local coordinate system (point b in Figure 1).

  6. Yb, global Y-coordinate of a point on the X1-axis of the local coordinate system.

  7. Zb, global Z-coordinate of a point on the X1-axis of the local coordinate system.

Second line (optional; if not provided, the Z-axis direction remains unchanged, and the X1-axis is projected onto the (X, Y) plane)

  1. Xc, global X-coordinate of a point in the (X1, Y1) plane of the local coordinate system, on the side of the positive Y1-axis (for example, point c in Figure 1).

  2. Yc, global Y-coordinate of a point in the (X1, Y1) plane of the local coordinate system, on the side of the positive Y1-axis.

  3. Zc, global Z-coordinate of a point in the (X1, Y1) plane of the local coordinate system, on the side of the positive Y1-axis.
