Hello,

Can a CHT simulation be run with Ideal gas equation of state and 2eq turbulence models like KE, KW, KW-SST? I am able to run the case with SA model, but when ever is use the previously mentioned 2eq model I get the following error:

acuRun: *** ERROR: error occurred executing acuSolve" 

I am restarting my run from a constant density simulation which was run till convergence.

I have  tried this on 2019 and 2020 versions of Acusolve. 

 

Thank you.
