In the UNDEX simulation on a simple steel plate, the stress in the plate does not converged but the pressure of acoustic medium reach a peak and converged. I put the pictures below. Does any one know why it is happened?
Not really enough information to understand your problem let alone help you with it. Why don't you post a short document of explanation?
There are many Finite Element softwares that are some commercial and some not. Many of them are open-source and some are closed-source. Abaqus, Ansys, LS-DYNA and ADINA are familiar to all...
