I’ve been trying the get the hang of SimScale over the past few days by trying to do some fluid dynamics analysis on an axial compressor, I’ve tried 3 different geometries, tonnes of different meshes, and a whole lot of changes to the numerics but I keep getting a ‘max iterations reached’ error, the residual plot has changed as I’ve tried more fixes but currently only my epsilon residual is decreasing. No simulation has passed 3% yet.
Trying to model an axial compressor (Originally I used moving walls but I dropped it since I figured they may have been giving my ‘max iterations’ issues)
Inlet -> 40m/s air flow
Outlet -> 15bar
I feel like there’s one little obvious thing I’m doing wrong but I’ve changed the other relaxation factors as recommended by other tutorials. If anyone could give it a look I would really appreciate it.
Originally I was having errors with my epsilon residual being the only one not decreasing but as in the failed ‘run 1’ now epsilon is the only residual that is decreasing.
Run 1 is a failed run using k-epsilon
Run 2 is a quick run that I’m doing now, the convergence plot shows that It will likely fail
Also just a heads up this isn’t my can file, I got it form the link in the description
