Use the Prescribed Normal Mesh Displacement node () to specify the displacement of the boundary in the reference normal direction. The node can be used on the boundaries of deforming domains. No constraints are set on the tangential displacement.

For common boundary condition settings, see Common Boundary Condition Feature Settings. The Prescribed Normal Mesh Displacement condition allows all constraint types.

Enter a value or expression for the Prescribed normal mesh displacement dn (SI unit: m).
