Hi, as an intern student, I'm modeling the effect of underwater shockwaves on a metal sheet. My model is dynamic and explicit. I succeed to simulate this effect for 5Mpa wave magnitude pressure. But in reality, this phenomenon has peaks of pressure around 300Mpa.

Thus when I increase the shockwave magnitude of at least 20Mpa, there are errors like Excessive node rotation. I tried to reduce the time scale factor to make my model converging, but it doesn't work.

HELP PLEASE !
