No rating yet Subject: Re: Regarding substructuring Author: Somesh J. Ghunakikar Date: 2002-03-07 21:10:00I have a single volume meshed with 50000 elements, I can not solve in generation pass, its coming out by giving watson error. Since the frontal solver can solve only 50000 DOF's. The problem is I can not divide the volume also. Again in the use pass, while solving its taking only frontal solver. But I need atleast sparse. I need an iterative solver in the use pass. How I can do it.
Thanks
