Nastran-Interface manual
This section describes all options that the user can find in the menu Constraints
MENU SEQUENCE:
Allows assigning prescribed displacements and rotations around global axes.
These conditions can be assigned over points, lines and surfaces, and affect nodes.
X-Constraint->Prescribed displacement along X-global axis
X-Rotation->Prescribed rotation around X-global axis
The prescribed displacements and rotations always make references to global axes.
MENU SEQUENCE:
Assigns enforced displacements or rotations. The signs convention for components of a vector follows the right hand rule (see figure below).
This condition can be assigned over points, lines and surfaces, and it is attached to nodes of the entity.
