Fixed Constraint (Thin Layer)
The Fixed Constraint and Prescribed Displacement (Thin Layer) nodes are similar, in that the prescribed displacement of the structural part on which it is acting is prescribed to zero. The displacements and rotations are prescribed to zero in all directions. There are no settings for this node. See Fixed Constraint.
