Joints via Constraints

Customers may want to run an ANSYS Workbench Mechanical modal analysis for a model with millions of degrees of freedom, solving for hundreds of modes. The Supernode solver can be chosen in Analysis Settings in Workbench Mechanical, but will not in fact be used in a model with Joints that employ MPC184 elements internally. The Supernode solver cannot be used with a Distributed solution, either—symmetric multiprocessor should be chosen instead, and an appropriate number of CPUs be specified.

Video: How to model joints via constraints in ANSYS

A substitute for joint-like behavior can be constraint equations between the two remote points that would normally be used in a joint. This video illustrates details in a model for which constraint equations imply a revolute joint, but permit the Supernode modal solver to be used.
