[STRUCT] sparse solver must be used if MPC184 elements
I'm using Mechanical Application [workbench[ V17.
I have a model where I want to output average rotation of the deformed shape in degrees.
I first tried adding a free body-ground joint to a face. Next I tried adding a remote point to the same face and hard-coding its tracking via command objects. In both cases, I get the solver error below. Solve time goes from ~2 minutes (PCG) to ~30 minutes (sparse out-of-core).
*** WARNING *** The sparse solver must be used if any current technology elements with u-P formulation or MPC184 elements using Lagrangian multiplier are included in the model. The equation solver option has been switched to the sparse solver.
Both methods are described here.

Is there any way to measure average rotation of a face, edge, etc. that DOESN'T require the sparse solver?

Andrew,
You could try adding the following command to allow using the PCG solver for MPC184 elements
PCGOPT,,,,,,,ON
