ABAQUS Keywords Reference Manual  

*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  

Type: Model data

Reference:
There are no parameters associated with this option.

Data lines to define a local coordinate system: 

First line:

  1. , global -coordinate of the origin of the local coordinate system (point in Figure 18.56–1).

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

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

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

  4. , global -coordinate of a point on the -axis of the local coordinate system (point in Figure 18.56–1).

  5. , global -coordinate of a point on the -axis of the local coordinate system.

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

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

  1. , global -coordinate of a point in the plane of the local coordinate system, on the side of the positive -axis (for example, point in Figure 18.56–1).

  2. , global -coordinate of a point in the plane of the local coordinate system, on the side of the positive -axis.

  3. , global -coordinate of a point in the plane of the local coordinate system, on the side of the positive -axis.
