Dear Gergely, are you using the same mesh for your serial run as for your parallel run? The mesh shouldn’t require much more memory when it’s distributed. If your serial code runs fine, the same code should also run fine in parallel (at least the basic part. If you don’t have some particular

Dear Gergely, if the mesh fits into memory, you don’t need to do anything special for parallel runs since the default grid manager will call grid.loadBalance() which distributes the grid. The grid data helper also automatically distributes user data like element markers, in case you are using

Dear Dumux community, I'd like to ask a question about mesh decomposition. I have a gmsh mesh (.msh) for a simple conduction model that runs without problems serially using ALUGrid. Is it possible to decompose that mesh for parallel runs or is there a workaround with a file conversion maybe
