HAI,
Why i'm getting this kind of message when fluet mesh to export to openfoam ? Code:

Quick answer: Depends on the format version of your Fluent mesh and it also depends on the version of OpenFOAM you are using.
Those messages can either be ignored or are already fixed in one of the more recent versions of OpenFOAM. Either way, please provide a simple example Fluent mesh so that we can reproduce the same error message.

Thank you for replying.
This is gas - gas mixing model. Using Fluent version 16.2. Openfoam version 2.4.0. I have changed the boundary condition according to fluent mesh. But still openfoam can not run the fluent mesh. What can be the reasons ? |

Quick answer: Unfortunately you haven't provided enough information to diagnose the problem.
Please follow the steps written here: http://www.cfd-online.com/Forums/ope...-get-help.html - this way it will be easier to diagnose the problem. Otherwise, you're asking for us to guess what the problem is out of more than 1000 possible reasons as to why your case is not working on OpenFOAM . |

Hai,
Now I have this issue corant number rising continuesly give error massege, I'm using icoFoam solver. following error massege comes, what can be the reasons ? Code:
