Hello:

I setup my boundary condition with pressure-inlet and outflow-outlet, but when I initialize, the result of the initialization didn't have result. I don't know what is the reason, could some one help me?

The result shows like this, it said the pressure information is not available at the boundaries. What should I do to fix this problem?

Many thanks

Hi,nI believe you cannot use together the pressure inlet and outflow boundaries. Try to set mass-flow outlet or pressure outlet instead.n

Thank you very much, I will change the boundary condition.n

And do NOT use the old outflow boundary with compressible flow. It dates back to the early Fluent solver when density was a fixed value and shouldn't really be used any more. n

Try to set Outelt as a Pressure Outelt.nnRegards,nnFedericon
