I am trying to convert a Fluent mesh of a laminar flow in a straight 3D pipe, with an inlet velocity of 1m/s in the negative Z direction. When using the command "fluentMeshToFoam" my command window looks like this, with the following error;

student@ubuntu:~/foam/student-4.1/run/straightPipe3D$ fluentMeshToFoam straightPipeFluid.cas

FOAM aborting

I have used the command before for other 3D fluent meshes and have successfully converted them to a Foam mesh so I am unsure what I have done incorrectly this time, any help will be greatly appreciated.

Thanks!

May be a bug in FOAM-Extend?

I think you can bug ticket there: FOAM-Extend bug tracker

Thanks for the reply



I think it had something to do with FOAM being unable to convert a Fluent mesh that has been made into a poly mesh. I tried this again but left the Fluent mesh as tetrahedral and this seems to work, so I'm assuming if you want a poly mesh then this has to be done after the Fluent mesh has been converted.


Kind regards
