Hello,
after computing pitzDaily case in openfoam I converted the results by using foamMeshToFluent and foamDataToFluent and recieved .msh and .dat. In Fluent I can see velocity vectors and pressure contours. But when I click Report -> Result Reports -> Fluxes and I choose inlet and outlet and push compute, the mass flow through inlet and outlet is zero. Where is the mistake? |

Hello Foamers,
I have the same problem: converting Foam results with foamDataToFluent gives a zero mass flow rate at inlet and outlet even if the rest of the results looks fine. The problem for me is that I can't add a UDS transport at the inlet because it is not advected by the flux. It seems like the data conversion missed the flux or the density. Did anyone face this problem and resolve it? Thanks |

You might have to correct your system/foamDataToFluentDict. What are your settings there?
I use the following Code:
p 1; U 2; U.X 111; U.Y 112; U.Z 113; T 3; h 4; k 5; epsilon 6; gamma 150; |

I contacted Ansys Fluent support, and the answer they gave me is that when you convert the data, each cell of the mesh receive its value, but the flux and gradients must be rebuilt, and the only possibility to do that is by restarting the calculation with Fluent. In short, with OpenFoam results converted to Fluent, we can't have direct access to some result reports such as mass flow through surfaces. |
