*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.

, global X-coordinate of the origin of the local coordinate system (point a in

Figure 18.56–1).

2.

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

3.

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

The following entries are not needed for a pure translation:

4.

, global X-coordinate of a point on the

-axis of the local coordinate system (point b in

Figure 18.56–1).

5.

, global Y-coordinate of a point on the

-axis of the local coordinate system.

6.

, global Z-coordinate of a point on the

-axis of the local coordinate system.

Second line (optional; if not provided, the

Z-axis direction remains unchanged, and the

-axis

is projected onto the

plane):

1.

, global X-coordinate of a point in the

plane of the local coordinate system, on

the side of the positive

-axis (for example, point c in Figure 18.56–1).

2.

, global Y-coordinate of a point in the

plane of the local coordinate system, on

the side of the positive

-axis.

3.

, global Z-coordinate of a point in the

plane of the local coordinate system, on

the side of the positive

-axis.
