Reply To: Pressure Inlet
Whether the boundaries are straight w.r.t. to the lattice is not relevant for the choice between Bouzidi IBB and other approaches (Bouzidi just places the wall at an exact specified intersection between two cells, this also works for non-curved walls). I suspect that the boundary geometry used for Bouzidi was not set up correctly in the case where you see the broken pressure behavior. Bouzidi and pressure boundaries can definitely be used in the same simulation (e.g. this is done in both the nozzle and aorta example cases).
