I tried converting the same .msh file using fluemtMeshToFoam and it worked fine. I'm wondering what might have caused it?

Hello,

I'm getting the same kind of error with fluent3DMeshToFoam and OF-1.5. I did not try the fluentMeshToFoam yet.

My mesh is generated with gambit-2.2.

Mattjis, i can send you an http link with my .msh, but it's quite big (more than one million cells).

Regards,

Etienne.

Hi, I got the same sequence of errors when using fluent3DMeshToFoam when using OF1.5 but it all went smooth with the OF1.4.1. Did anything change in-between, some lib somewhere?
Just for the record, if it helps:

We are now using flex 2.5.35 which comes with SuSE 11 and other recent Linux releases or can be downloaded and compiled from sources. There is a bug in the .skel file in version 2.3.33 (fixed in 2.5.35) which means that "]]" in the "C" code throws and error but "] ]" is OK. The fix I uploaded should solve the problem for you.

Hi,
So this means I've got to check out the files with git and compile them manually? This may be hard because my linux-system doesn't have a connection to the Internet.... I'd be glad if I could download a compiled 64bit version of this new fluent3DMeshToFoam so I can convert my porous zones from fluent to OF. Otherwise I could try to use the 1.4.1 version, but I'm quite happy with 1.5 and don't know if it's possible to use fluent3DMeshToFoam in version 1.4.1 and then run in 1.5.

Regards
Wassja

I met the same problem, and using the new fluent3DMeshToFoam.L works, Thanks

3D fluent mesh
 

Dear friend,

you can do the remeshing starting from lines, areasand then volume mesh. you will get the 3d mesh only after error free 2d mesh.Try again.

Hello,

I am new in OpenFOAM and I´m trying to convert a 2d mesh (.msh) from Fluent to OpenFOAM usinf FluentMeshToFoam. (OF 1.7.1.)

I got the same error "SigSev" and also "Printstack".
