*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.

Products: Abaqus/Standard  Abaqus/Explicit  Abaqus/CFD  Abaqus/CAE  

Type: Model data

Level: Part,  Part instance  

Abaqus/CAE: Not applicable; instancing a part in the Assembly module creates a local coordinate system.

Reference:
There are no parameters associated with this option.

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 18.64–1).

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

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

    4. 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 18.64–1).

  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 18.64–1).

  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.
