Absence of Table generation (real gas)
 

Hi there!

I'm trying to simulate refrigerant R-245fa in ANSYS CFX as a real gas with the Peng Robinson model. I tried with the default temperature and absolute pressure limits for the table generation, but when iterating, the calculations fell out of the limits and it did not converge.

I just tried not activating the table generation limits. A warning appeared, which I just ignored... The solver converged and found a result.

The results are not very satisfying, but I think it should be a problem with the Cp coefficients.

My question is: Is it Ok not to set limits for the table generation and ignore the warning?

Thank you very much ;)
