How are the displacement constraints (D commands) in .CBDO file related to PRNSOL displacements at the CUTBOUNDARY nodes if the nodes are coincident (at cutboundary) in the coarse and the Submodel ? i.e. What is the logic of Interpolation of DOF values at these coincident nodes between the coarse and finer submodel?

Solution: In CBDOF command ANSYS first issues NMODIF commands (solid-shell submodel) and then issues D commands. The point to note here is that the D commands are in these rotated nodal CS and not in global CS. However the final results (PRNSOL) are reported in global CS. Thus to compare the D values in CBDOF and in PRNSOL, one has to apply rotational transformation to get them in same CS. ANSYS follows standard Transformation laws here.
