Reply To: Total pressure is not equal to the sum of static pressure and dynamic pressure.

Apologies, the notifications are still alittle unreliable and I took Friday off. 

Looking at the results I suspect part of the problem is the mesh. The jump in cell size from inflation to free stream is too aggressive. Look at the Total Pressure contours on the outlet to see the visual clue. 

Plotting velocity vectors on walls tends not to be overly useful: think about what the velocity is on a wall. Post processing medical models is always difficult, but one trick is to look at "transform" in surface creation and/or use boundary registers to split the domain to get an interior at the edge of the inflation layer.
