Q) I'm running a simulation of a recirculation system, i.e. no net in- or outflow, but with a moving wall driving the flow. I have seen in the solver that the pressure is automatically set to zero in one point, but I would like to know if I can specify the location of this point in CFX-Pre? A) This is set in Solver Control/Advanced Options/Pressure Level Information. Change Automatic to Cartesian co-ordinates. For multiple domains, there is a pressure reference point for each domain.
