How to explain total pressure less than zero?
 

Hello,

It is quite often for me to see in my simulation (incompressible duct flow) some region of the flow has negative total pressure. Any one can help to explain what happen in the region with negative total pressure? Why?

It was analyzed in steady state not in transient state.

Thanks

Hi,

CFX-Post displays relative pressure instead absolute pressure. Watch out with this.

In order to avoid this situation , Please set your reference pressure higher.
