Technically this would be possible, but the DofMap is not set up that way right now.
Since the sparsity graph takes up some nontrivial size, we compute it, inform the matrices in the problem, and then delete it. So, for the current setup, I believe what you want to do instead is attach a user provided matrix to your system. It will then inherit the sparisty pattern at the appropriate initialization / refinement steps. -Ben ----- Original Message ----- From: Anthony Han <[email protected]> To: libMesh <[email protected]> Sent: Sat Jan 16 04:23:06 2010 Subject: [Libmesh-users] About sparsity pattern Hi, all Is there an easy way to extract the sparsity pattern of a sparse matrix. I want to construct a new sparse matrix based on it.
