Thank you it works. But why? It seems that I just add a symmetry, and I think the result is supposed to be the same, right?


Besides, And there two another problems.


1. the result seems not symmetic in the corner. I think the result is supposed to be symmetic in the whole body.


2. It warns that "for a  linear analysis newton raphson type has been activated. The solution may not converge. For better results use program controlled." Where should I use program controlled? I tried use time step as the program controlled, but the warning is still there.
