18.56 *SYSTEM: Specify a local coordinate system in whichto deﬁne nodes.

Thisoption is used to deﬁne nodes by accepting coordinates relative to a speciﬁed local rectangularcoordinate

system and generating the nodal coordinates in the globalcoordinate system.

Products: ABAQUS/Standard ABAQUS/Explicit

Type: Model data

Level: Part, Part instance

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 sy stem (point ain

Figure 18.56–1).

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

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

The following entries are not neededfor a pure translation:

4. , global X-coordinate of a point on the - axis of the local coordinate system (point bin

Figure 18.56–1).

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

6. , global Z-coordinate of a point on the -axisof 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 coordinatesystem, on

the side of the positive -axis (for example, pointcin 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.
