[Libmesh-devel] DofMap::compute_sparsity_pattern()

[KIRK, B. (JSC-E. (NASA) <ben...@na...>]

I've just committed some changes to the way the DofMap computes the sparsity
pattern for sparse matrix preallocation.  This change seems timely since,
especially for large systems in 3D, the old approach could be quite slow.
This is especially important for AMR the sparsity pattern must be rebuilt
each time the mesh is refined.

John, I believe this should be especially helpful for some of the Porous
Media stuff you have been working on.
