FLUENT: Divergence in AMG solver when using Enhanced Wall Treatment although y+<1>

Hi all,


I run a pressure based external flow simulation (flow around a delta wing at M=0.1 at 20 deg angle of attack). I wanted to use the Linear Pressure Strain RSM with Enhanced Wall treatment as my y+< 1. I can run the RSM when using the standard wall treatment fine but as soon as I put it on enhanced I get divergence. This is not the case when running k-epsilon though. I was wondering why this happens and what I can do about it. I really would like to run the epsilon based RSM with enhanced wall treatment.


Thank you very much in advance for your help

Better to the omega based RSM. Try that at first.
