when the real gas is selected in numeca, how to set the parameters of the gas?
why can the effiency reach to 1.5? Is it not perfect in computing the case with real gas? who can help me, which used to compute the case with real gas? Thank you!!! |

Hi,
The description of your problem is not complete enough for us to help you. The way to define a real gas computation is fairly straightforward in FINE. If you are using a user-function to define the law of the real gas, you should check that the format of this function is correct (see the User Manual). In any case, an efficiency of 1.5 is just impossible to get, so there must be something wrong there, whatever the gas properties are : is the computation converged ? are you using correct efficiency definition, etc..? As I said, the description of your problem is too light to help you. If the problem persists, I would suggest you contact your NUMECA support office immediately. Thanks, bruno |

the problem that I met has been resolvable.
and the profile of Cp is incorrect. By the way, where can i find the details of state equation in computing the real gas? There is no the information about it in the User Manual. |
