The CFX documentation does not go into details like what pressure boundary it uses on walls. But I am pretty sure it is dp/dn=0. And you are correct, for a small number of flows this is not correct...

The documentation states that the flow direction is required because the inflow direction uses the total pressure. Thus the flow velocity is required and a...

The pressure averaging procedure is described in the documentation. So what is not clear from that? A correction to my previous post - the...

The outlet condition (in pressure mode) simply applies the specified pressure and zero normal gradients on most other variables. This is accurate in fully developed flow but does cause an issue where...

The flow boundaries which are implemented in CFX are fundamentally of two types - velocity and pressure. Which ever is defined, the solver works out the other. CFX does not give you the option to...
