Hi, i have to make multiples spheres cooled by air, i tried to modify this tutorial from theo ong https://github.com/theodoreOnzGit/Op...eOil_kOmegaSST

I included 8 spheres in a .stl file, but now running chtmultiregionfoam it crashes, where is the error?

i attach the chtmultiregionfoam log, and the case here: https://www.dropbox.com/s/u0yrkb19t9..._oil3.zip?dl=0

For some reason now chtMultiRegionFoam woks, i only changed maxCo to 1. The sphere region currently contains only 1 sphere, how i expand it to contain the 8 spheres?
