FIXSHLROT,[stiff]

This command applies soft springs to all nodes that are connected to coplanar shells. The overall spring stiffness is determined by the stiffness argument of the command and applied along the normal shell's plane. This command in combination with FIXSLDROT, and FIXSPRROT is an alternate to FIXROT that more closely approximates stiffness matrix for a models that are generated by ANSYS®.

• stiff – Stiffness of springs added to shells to remove the singularities. (default stiffness 10)
