Use a Mapped System (
) to create a coordinate system that defines a mapping from the frame coordinate system.
If this coordinate system is added as a subnode to a Combined System node, define where it will be active using a selection in the
Geometric Entity Selection section. Also, the
Name and
Coordinate names fields and the
Frame list are not available in this case.
The Frame list is the same as for the
Cylindrical System.
Under Coordinate names, the default names appear in the
First,
Second, and
Third columns —
x1,
x2, and
x3. In planar 2D models,
x1 and
x2 are typically the in-plane coordinates, and
x3 is the out-of-plane coordinate. Change these names if desired.
Under Coordinate mapping, the
Coordinate column displays the
Coordinate names with the
Expression column displaying the associated mapped coordinate.
If required, select the Assume orthonormal check box. The program then uses the assumption that the settings define an orthonormal coordinate system.
