Ansys simulation

Hi,all

       Recently,I met some problems about intendation simulation with Ansys.My simulation consider failure and large deflection.But the elements happen to distortion when the defelction became very large. So I have a confusion about how to handle the element distorted. Who have any idea about that? 

       My simulation is a quasi-static problem, How to use Ls-dyna to simulation this problem if the Ansys can't solve the element distortion efficient? Thanks a lot!
