Reply To: Carotid Simulation – no flow through one branch of bifurcation
This is most likely caused by the outflow layer being non-axis aligned and “too thin”, causing the staircase approximation to only be realized partially. The geometry should be better if you increase the cylinder length (which you already tried) so the issue is probably that the wall of material 2 that the call renames is also incomplete.
However, depending on the boundary condition (i.e. if you use the default pressure boundary) you will need to rotate the geometry s.t. the outlet is axis aligned anyway as pressure boundaries are tricky in such situations (one common approach is to flip velocity and pressure boundaries s.t. there is only a single pressure inlet and multiple (not necessarily axis-aligned) velocity outlets.
