Constraint Options
The following table shows which constraint options are available for each model type in a Cartesian coordinate system:
|
Model Type
|
Constraint Options
|
|---|---|
|
3D
|
Trans X, Trans Y, Trans Z, Rot X, Rot Y, Rot Z
|
|
plane strain and 2D axisymmetric
|
Trans X, Trans Y, Rot Z
|
|
plane stress
|
Trans X, Trans Y
|
 |
The software ignores any rotational degrees of freedom for 2D solids or solids in 3D models. If you specify constraints on Rot X, Rot Y, or Rot Z for these elements, the software ignores the constraints.

The software labels the coordinate directions differently if a cylindrical or spherical coordinate system is active. The following table shows the constraint options for each coordinate system (R=radial, T=theta, and P=phi):
