Hello! I tried to compile an advection diffusion form using Streamline Upwind Petrow Galerkin stabilazing method, similar to the one introduced in DOLFIN 0.6.4. Using 3 dimensional and first degree Lagrange elements, FFC/g++ chokes when the produced code is compiling. It wont finish compile... Is this a known problem and a limitation of FFC/g++?
In PyCC I use DOLFIN to assemble the same system matrix, but instead of using one form for the whole system I split the form into at least 4 different forms. These compiles smoothly and after I have assembled the matrices I just add them together. This approach is not possible using the present DOLFIN linear algebra interface, as sum of matrices is not supported. Is this something we want for the future?
