Matt_h,

I'm facing the same problem.
I've tried to use the ideasUnvToFoam of OF v2.2.2 but got the same error message :

ideasUnvToFoam: ideasUnvToFoam.C:1271: int main(int, char**): Assertion `noveau > -1' failed.

I applied the patch and recompile the ideasUnvToFoam without more success.

Any tips, this bug is driving me insane ...

Thanks for your help
Have a nice day

François

[Matt_h]

well francois, my problem was a simple error in that I had named one of the faces twice...it took someone else to have a look at the output and point it out, then it was obvious.

Sorry I can't help much more than this!

[francois]

Thanks Matt_h for your kind answer.
It looks like that the problem arise when the group of faces (named "Fin" in my case) is regonised as a faceZone.

I've tried with and without this group of faces in salome and the following error only appears when there is this faceZone.

This is the error message I get when using the internal group of faces "Fin" in Salome 6.6:

0: Fin is faceZone
1: Cyclic1 is patch
2: Cyclic1_mirrored is patch
3: Outlet_final is patch
4: Inlet_final is patch
5: PipeWall_final is patch

    Cyclic1     150
    Cyclic1_mirrored    150
    Outlet_final        100
    Inlet_final 100
    PipeWall_final      400

Matt_h, please could you send me your hdf or Salome python dump file for testing purpose ?

Or can someone send me a working example with a inner baffle to try to understand what's wrong with my however very simple case .

Thank you very much for your help.
Cheers

François

Hi Matt&Francois. I have the same problem.

my geometry and mesh groups were created in salome-meca and seem to be ok. no duplicate faces or extra edges. when I use ideasUnvToFoam,terminal issues warning:

1: outlet is patch

3: top is patch

how did you manage to fix it? what do you mean by "put top_bottom" twice??

Hi All

I am new with Salome and OpenFoam and I have similar problem with internal faces, i am tried to simulate a Sump Pump and i am making my geometry in Salome 6.6.0. My mesh was created using Partition operation.

After that i tried to Convert it with ideasUnvToFoam but throws me an error with internal faces

I would greatly appreciate any advice as to how to work around this problem, i am tried not to use the partition operation but i need maintain the two separate solid.

Hi,
Did you try to apply the patch ideasUnvToFoam.patch ?

Hi Laurentb

Yes, i already applied the patch, but i'm still having the trouble.

Any suggestions?

Hi at all,
I want to import files from Salome to OpenFoam with "ideasUnvToFoam". It is working with easy geometric shapes but when it is getting a little bit more complex there is coming the following message in the shell:

Can anybody tell me the meaning or what to do next?

Check patches again in salome. On two patches you might have given same name.

I solve the same problem by check and make sure different patches don't have same faces.

[teodm]

I have the same problem.my geometry is a wind tunnel with two wings inside of it.When I run ideastofoam for my mesh it recognizes the wings as cellzones not as patches.I hope someone helps with the situation.thank you in advance.

[cfd_user_pune]

This type of error comes when you change something in patch names (Geometry > Create Groups) after completion of mesh.
To solve this you need to delete all patch names under Geometry and assign them again. Create new mesh under mesh module.

Hope this will help someone
