Prescribed Displacement

The node adds a condition where the displacements in one or more directions are prescribed for the porous matrix domain, boundary, edge, or point (depending on space dimension). The condition can be added from the submenu and it can be combined with any of the conditions found in the submenu.

If a displacement is prescribed in one direction, this leaves the porous matrix free to deform in the other directions. The condition can be added from the submenu and it can be combined with any of the conditions found in the submenu.

•

If a prescribed displacement is not activated in any direction, this is the same as a constraint.

•

If a zero displacement is applied in all directions, this is the same as a for the porous matrix.

Coordinate System Selection

The constraints are applied in the directions of the coordinate system selected in this section. You should only use a coordinate system that has fixed spatial directions.

Prescribed Displacement

For the displacement in each direction, select or . With (the default) the displacement component is left unconstrained. Use to constrain the displacement to a given value.
