Divergent behavior of FastTetrahedralCorotationalForceField #4594

Open ScheiklP opened 1 month ago

ScheiklP commented 1 month ago

Problem

With the same exact parameters, FastTetrahedralCorotationalForceField shows unstable behavior, compared to TetrahedralCorotationalFEMForceField.

Expected behavior I would expect both components to show the same behavior, or at least to be stable.
