Description:

Allows node displacements to be given to edges, faces or points, using the three directions of a local register mark. Such displacements can, for example, be the outcome of experimental observation.

General principle:

Select the locations to which displacement is to be applied, using the and buttons.
Validate your selection by clicking on .
Enter the translation and rotation displacement axes (use the and buttons to switch from one mode to the other). Rotation displacement only applies to surfaces, so this option only appears when the part undergoing displacement comprises a surface. Translation displacement is entered in a unit that is compatible with metres (m). Rotation displacements are entered in a unit that is compatible with radians (rad).
Select a reference register mark in the working space, or click on .
Set the boundary condition annotation text or click on .

Optional point(s):

Points can be directly designated or meshing nodes displaced using the button. Select one or several points, then enter the displacement axes and the reference register mark in the same way as for the edges and faces.

In order that the point(s) of this boundary condition in the middle of a face, edge or beam is/are correctly processed, the meshing of the displaced geometry is re-run.

Specific point(s):

Displacement is shown as register mark oriented in the same way as the reference mark, each end of which represents translation blocking as a straight arrow and rotation blocking as a rounded arrow.

Displacement is automatically put in the "BOUNDARY CONDITIONS SET" at the time it is created, and can be edited at any time in the symbolic tree .
