The second archive failed to converge during the transient step 3.
The corrective action is to put 6 linear elements across the thin beam in the 2D Plane Stress model OR switch from 2D Plane Stress to a 3D shell model.
I managed to get 6 linear elements across the 2D beam just using the Proximity Mesh control.
That model is running now.
I showed you how to make a 3D shell. That may have less convergence problems, but it will surely solve faster.
