| The main solver for LinopMat. Read about class BcMat to see how this works, also see examples example/Ex_16.cpp and test/Visco_3D_pipe.cpp of how this is applied. This function is useful when boundary conditions are mixed between variables. Also, if you have boundary conditions that have an associated eigenvalue, see compute_with_constraints. More... | |
