Hello Jan and Johannes, Thanks for the response. Are the demo mentioned below available and plug and play type with just scripts available ? Or does it assume some developments ... (meshing, boundary conditions ...) My demo is in 10 days, so there is not much time left for me then. Alain

There are demos of coupled problems (like Stokes, Navier-Stokes, mixed Poisson, biharmonic, Cahn-Hilliard), solved both iteratively and fully-coupled, in a directory tree. Proper multiphysics, i.e. mixing unknowns on distinct meshes, is not supported yet, but it is in the focus of developers. Usual workaround is to define all the fields of a mixed problem on the whole domain and restrict them by an application of DirichletBC by arbitrary value at spare regions. This can be a little bit tricky sometimes. There are also more advanced approaches like telling to PETSc what is null space of your operator (like in singular-poisson demo). On the other hand if you decouple your problem into a sequence of single-mesh problems, then you can solve coupled problem iteratively without any workaround.
