Good year everybody,
sorry for my bad english...

I successfully meshed a multi domain with Fluent 13 mesher and then used it in OF1.7.1, but, i love open source then I am looking toward the capabilities of snappyHexMesh in multi doamin meshing.

The geometry is very simple, an heated pipe and a cold fluid through it.

I have follow this steps for case setup (reported in past post) based on
snappyMultiReginHeater tutorial (in OF-1.7.1)

1) copy the case dir in the working folder.
2) modify the blockMeshDict (whole domain)
3) replace the stl files by SOLIDO.stl and FLUIDO.stl. stl files are obtain by exporting SALOME geom.
4) modify the regionProperties.
5) modify the snappyHexMeshDict to fit the new stl files.

When I launch SHM the background mesh don't diasappear and it creates a domain0, SOLIDO and FLUIDO mesh.

I have read thousand post and i:
-modify the locationInMesh (pointed in FLUIDO, SOLIDO and domain0)
-increase background mesh quality
- etc ..
but without success!!!!

PLEASE HELP ME!!!

Do you know how to delete the domain0 mesh?

Thanks
