Hi All,

I am trying to model a simple open valve chamber with two incoming pipes, i am using interfoam and have had some success with preliminary models. However, the time to complete is horrendous and i am trying to simplify the model by using a coarser mesh with the internal parts of the delivery pipes simulated as internal patches rather than walls.

I have created the model and the mesh in Salome 6.5.0.

The problem is with ideasUnvToFoam when i carry out the conversion to openFoam and i get the following message:-

ideasUnvToFoam: ideasUnvToFoam.C:1269: int main(int, char**): Assertion `noveau > -1' failed.

The converter is failing on the right face zones element - does anyone know how to solve this ? I'm willing to alter the code for ideasUnvToFoam but ive no idea where to get my hands on a specification for the two file formats IdeasUNV and openFoam. In particular since my conversion software won't successfully convert anything with a cell zone ive no ides what the cellzone file should look like.

Has anyone solved this problem ? Can anyone point me to a specification for the IdeasUnv and OpenFoam file formats ?:confused::confused:

Thanks for any help you lot can offer..
