Hi!
I have a strange error: when I start iterating my file, following message appears: Error: cx-xy-plot-data: invalid number Error Object: nan When I try to display results: Error: cx-set-real-entry: wta[2](float) Error Object: nan What is the problem??? The BC are quite simple (mass flow inlet), the grid check is ok. There is no udf or something like that.. The file has about 1.500.000 cells - I hade simulations running with a similar number of cells. I can display the grid. Any Idea??? |

I forgott the strange thing:
after I start iterating, Fluent gives the message given, but it seems to iterate!! It plots the "normal" message for this king of geometry: reversed flow in 1740 faces on pressure-outlet 156. |

Hi!
I solved the problem: it seems to be, that there are two faces on the same place (but other than normal, Fluent doesn't told me when reading the grid). Another reason could be, that an outer bondary face was defined as internal. Now, simulation is running very fine... Thanks for reading Ralf |
