Dear member, I am going to do FEM simulation for our electronic packaging. There are several software in the market, such as ANSYS, MARK, ABACUS and Pro-mechanical. From your experience, which one is better? I need to simulate the nonlinear material and very fine structure such as wire and adhesive. Pls. give me some advice.
