convergence issue
 

Hello

I am trying to solve a simple laminar flow problem with total pressure inlet and static pres and entrain opening BC, i have five cases to solve with 0.1, 0.3, 1, 3, 10 bars as inlet BC and 0bar pressure for opening.

i am able to get convergence for first three cases but not for the other two, i am using a structured mesh with high resolution advection scheme.

any suggestions to achieve convergence

Thanks in Advance

Hi,

Have you considered that at 10Bars the flow may no longer be laminar? If so a turbulence model will be needed.
