nYou have the undeformed geometry, and data on the displacement of points on the surface of a body after loading.nIs that X,Y,Z displacement data of reference points on the surface?nIs this some sort of pressure load, so there is pressure on all the surfaces?nOr is the load applied to a limited subset of the surface of the body?nIs the material in the body isotropic?nAs Erik says, you can apply enforced displacement to a body surface.nSince the body is discretized into nodes and elements on the inside of the body, there is still a need to invert the stiffness matrix to obtain the solution of the displacement of the nodes inside the body.n
