Hi @yosukegb4
Out of curiosity, is there any way I can split my background mesh box ? Like say my inlet face (need that to define two inlet phases)?. The only way I can import my model with an external domain is by using step or iges file formats but my surfaces always seem to faceted which leads to problems in meshing. STL format allows me to import my model as a single face alone, so I am unable to import an stl with an external domain. @dheiny I had a look at this discussion Collaborative simulation project? Multiphase flow around a boat hull - #45 by quequen and I am facing a similar problem. Is there any tool which allows me to combine these multiple facets into a single NURBS surface ?
Cheers,
Cecil
