First, select the vertices or edges one by one using the left mouse button, or by dragging to select an area. Then, click the right mouse button.

This opens the "Prescribed displacements" window. Here you can "Add", "Copy" and "Delete" displacements and rotations for each of the project loadcases.

Clicking "Add" creates a row in the table.

In the drop-down menu in the first column, select "Loadcases" from the list of available simple loadcases.

The table will then have a maximum of six additional columns, corresponding to the translations (Dx, Dy, Dz) and rotations (Rx, Ry, Rz) in the three spatial directions. The number of columns depends on the constraints or restricted movements at the selected nodes or edges.

Six additional columns are displayed at a fixed connection; three columns are displayed at a hinged connection; and a single additional column is displayed at a sliding support in a plane.

In each of these columns, you can enter the desired displacement or rotation value for the specified scenario. The units in which these values should be entered are indicated in the table header.

The assignment of prescribed displacements at nodes or edges results in forces appearing in the structure during the analysis, which can be viewed subsequently.

To include displacements or rotations in other loadcases, further rows are added to the table.

The forces resulting from the displacements or rotations inserted will be affected by the combination factors applied to the selected loadcase.

Finally, click "Accept". The nodes or edges with specified displacements will change colour so that they can be identified in the model.
