Hi everyone,

I’m running a steady-state simulation of a centrifugal compressor impeller and I keep running into an issue where the residuals settle but don’t properly converge, even after several thousand iterations. The solution...

I have been trying to run the the NASA HECC tutorial provided by TCAE. The tutorial has a very dense mesh and takes verylong to run and make a speedline. In order to save computation time I tried two methods:

1. I reduced the mesh and ran the simulation for only one point on the speedline (the one with the highest efficiency). 

2. I ran the whole tutorial as is and just skipped...
