Thank you, Mathias.rnA quick follow-up question on the aorta3d:rnrnIt seems that the definition of normal vectors for the inflow and outflow is opposite to the flow direction.rnThe normal vector is pointing away from the geometry at the inflow, but pointing into the domain at the outflow.rnHowever, the final solution seems to be fine with the right flow direction.rnrnUnfortunately, when I used the code on my own geometry, the flow was all backwards; flow was from the outflow to the inflow. I learned that it would not change anything if I reverse the normal vectors?rnWhat did I do wrong? rnrn
