INLET TOTAL PRESSURE problem initializing and problem - NX Advanced Simulation Thermal/Flow analysis

Experimenter

Hi,

 

we are managing to add NX Advanced Simulation thermal/Flow analysis to our daily design job keeping on some test on simplified solid bodies.

The topic to solve is related to: problems with setting TOTAL PRESSURE on INLET section.

No suitable solution can be obtained linked to conditions showed on image below:

Someone could please explain how we can SET THE PROBLEM in order to obtain some suitable solution without no-convergence errors or too low final total pressure values?

In last results we've found total pressure values of about 0.5 KPa to 1 KPa and that's not possible.

 

Thank You.
