For shape and bead optimization, only nodes belonging to elements supported by Tosca Structure can be used as design nodes, see About Design Variables (DV_SHAPE) and Design Variables (DV_BEAD) for details. More solver-specific information about the sensitivity-based algorithm is found in Remarks for Sensitivity-Based Optimizations. For sensitivity-based bead optimization, see Special Remarks Using Sensitivity-Based Algorithm. In ANSYS®, elements with pressure degrees of freedom are supported for acoustic analyses in the context of NVH optimization. Remarks
