ACE/ACI bug: disable/modify equilibration in mechanics problem #94

Open ikalash opened 1 month ago

ikalash commented 1 month ago

The mechanical problem initially solves for the equilibrium solution, which often results in very small time step sizes, and can also lead to long computational runtimes.

We believe this issue can be resolved by either disabling the initial equilibrium solve, or by reworking how this solve is done.
