The Prescribed Displacement node adds a condition where the displacements are prescribed in one or more directions to the geometric entity (domain, boundary, edge, or point).
Select one or all of the Prescribed in x direction,
Prescribed in y direction, and for 3D components,
Prescribed in z direction check boxes. Then enter a value or expression for
u0,
v0, and for 3D components,
w0. For 2D axisymmetric components, select one or both of the
Prescribed in r direction and
Prescribed in z direction check boxes. Then enter a value or expression for
u0 and
w0.
Click the General notation to specify the displacements using a general notation that includes any linear combination of displacement components. For example, for 2D components, use the relationship
For the H matrix
