meaning of pressure in CFX-Post
 
When I was drawing a pressure graph, I found the pressure value is not very high, does the pressure value mean relative pressure or absolute pressure? Thanks.

It means relative pressure based on the reference pressure set by you in the domains menu.

Be careful though. It is the relative pressure relative to the pressure in the CCL. That's usually close to, but not necessarily exactly, what is entered into Build. To save some frustration don't enter too many digits (ie more than 5) into Build. I think that confuses it.

CFX-Build, confused? No way, never. At CFX is stripping the physics out of build for 5.6. Hopefully that will aleviate such problems.
