Re: [HG dolfin] Use DofMap in FEM to get dof mapping and to compute number of nonzeroes per matrix row. This gives big memory savings for some problems. For /src/demo/pde/elasticity memory use was approx. 600mb, now 200mb.

Aha. Yes, that will be useful.

[HG dolfin] Use DofMap in FEM to get dof mapping and to compute number of nonzeroes per matrix row. This gives big memory savings for some problems. For /src/demo/pde/elasticity memory use was approx. 600mb, now 200mb.
