Hi cummunity, 

I am new to the ANSYS. I am trying to simulate gat jet with multiple holes for inlet as Helium flud. My pupose to obtained the profile in outlet. When running simulations in ANSYS Fluent, observing a good trend with a small number of iterations but then getting blank contour plots for density and pressure after a higher number of iterations. it looks simulation converging up to 25 iterations and start diverging afterward. Please help me shortout the issue. Thanks !

Some images will help. If it's diverging check the mesh (cell quality & resolution), and then boundary & model settings. If you post the images of the early part of the flow there may be clues as to what's going wrong.

Yes, that's diverging. Now, maybe some images of the flowfield at around 20 iterations?
