Hi,Stoki
I have the same problem when I try to simulate the MIT CO2 nozzle with an inlet near critical point. Hoever, once I open the nucleation model, it goes diverged all the time. Moreover, I can get a converged result with a superheating vapor inlet condition. I think clipping the critical radius to 1 nm from Ameli's paper in CFX may help.
I am wondering, if you can kindly show me how to write the CEL of clipping the critical radius to 1 nano meter. Look forward to your kind reply.
Best regards, Chen
