# Nodal Disp. Loads \[FEA]

Nodal displacement loads impose prescribed displacements or rotations at specific nodes. They are used to model support settlements, imposed deformations, or known displacements at boundary conditions.

**Load Case:** The analysis case (load case) to which this displacement load belongs. The displacement will only be applied when this load case is active in the analysis.

**Node:** The node at which the prescribed displacement is applied. The node must have the corresponding DOF constrained (fixed or with spring stiffness) for the imposed displacement to take effect.

**Tx:** Prescribed translation in the X direction. The node will be displaced by this amount in the global X direction.

**Ty:** Prescribed translation in the Y direction. The node will be displaced by this amount in the global Y direction.

**Tz:** Prescribed translation in the Z direction. The node will be displaced by this amount in the global Z direction (e.g., use a negative value to model downward support settlement).

**Rx:** Prescribed rotation about the X axis (in radians). The node will be rotated by this amount about the global X axis.

**Ry:** Prescribed rotation about the Y axis (in radians). The node will be rotated by this amount about the global Y axis.

**Rz:** Prescribed rotation about the Z axis (in radians). The node will be rotated by this amount about the global Z axis.
