Hello, I'm simulating a blanking operation in Abaqus/Explicit and right now I'm trying to figure out the optimum size of the smallest elements. My question is: do I have to simulate the whole blanking operation (which can take hours from a certain element size onward) in order to do a good mesh sensitivity analysis or can I just simulate only a fraction of the operation, like only punching half of the way, or a tenth of the way and still have a valid mesh sensitivity analysis?
Thanks in advance and feel free to ask for further information.

Well, mesh independence is usually done for most critical conditions, like highest velocity involved.
