Ideas for smoothing solid-flex contacts (PSHELL)?

Attached model drags a simple block across a simple flexible plate's surface. Force is too unsteady to be of any use. Even with flexbody rigid, force is unsteady.

I've noticed using SI2 solver dramatically helps, but hoping someone out there has other tricks up their sleeve (other than just softening the contact parameters).

The settings are indeed for the dynamic solver, it just starts with a static solution, which was not showing any obvious shortcomings.

If you have time/motivation, can you please run the simulation with the attached files as requested some time today?

Again, the goal would be a smooth contact force (50 lbf) from t=0 to t=1. I don't care if the plate is flexible, or made rigid. Really just care about getting smooth contact forces with the flex body's surface.

Instead, even at very low Error & Hmax, we see huge variation in angular acceleration about z-axis, after some time has passed.
