Dera Timo Koch, Yes, this example runs fine ( test_1p_incompressible_tpfa_quad ) here. I don't know if this issue is related to the Box method, but so far when I run a test using tpfa and mpfa the BlockDiagAMGBiCGSTABSolver works fine.
I am not confident the problem is precision-related also. But when I add up the flux (residuals) at the boundary nodes, I get a sum with a much smaller precision than 1e-16. It's when I try to evaluate the pressure gradients at the boundary faces and then use them to obtain the boundary flux that the sum becomes way more important. And as I need directional flow information, I think I have to work at the faces. Another test I did was to observe that as the fracture permeability gets closer to the matrix permeability this precision improves, so this might be a precision issue since the pressure gradient at the fracture-matrix interface is supposed to be very small (because the fracture is way more permeable). Well, if I can make this solver work I can verify this possibility.
