Allow a lot more substeps, such as initial=1000, min=10, max = 1e5. Set Newton Raphson residuals to 3 in the solution information to locate problems in unconverged solution. Show images of those contours.

View any partial results for partial deformation to see if the model is sliding off the rollers. Can you show a zoomed-in picture of the roller mesh and mesh on the plate where the rollers meet?
