Hi,
I have done a first raw run following my previous suggested points to check contacts and mesh quality.
1.6mm downwards with Pardiso. File converge in around 100 sec.
That’s the easy part but it shows you need to work on that mesh preparing more smooth edges of Punch and Base and refining the shell plate.
The mesh density is too low and there will be unmanageable peak stresses .I have reach 66 GPa.
