      In springback compensation, implicit method SHOULD be used to get quick and more accurate solution. The mentioned convergence issue might come from in appropriate setting. for example, element #2 is not as good as #12 in convergence. In addition, there are many implicit control keywords, which might also cause problems. To make it easy for user to use implicit springback simulation, user simply need to remove all the implicit keywords, and add the following:nn*control_implicit_formingn1nnThis keyword has been used extensively in springback analysis and we have not have any issues. nnExplicit springback analysis was popular before 2000. At that time, implicit method was not robust and memory is also a concern. The main drawback of using explicit method is that the result depends the termination, damping coefficient.n
