What types of stl files are needed in snappyhexmesh?
I'm trying to figure out how to take models from my cad suite (autodesk inventor), and use snappyhexmesh (or any other native openfoam mesher) for pre-processing.
Now, it was my understanding that for flows with an inlet and outlet, that I would need separate stl files as those surfaces. However, Inventor doesn't explicitly allow the exporting of surfaces to *.stl. Do I need to have just the inlet/outlet/wall surfaces to export, or can I make volumes? If I need to have surfaces only, it looks like I'll need to export the surfaces as STEP, and use a different program to generate STL files for use with snappyhexmesh, which isn't an especially enticing option. Also, do I need the whole volume of the flow channel as its own STL for snappyhexmesh? And how do I check if my stl is watertight? Any help here is very appreciated. Edit: from this page http://www.cfd-online.com/Forums/ope...e-stlfile.html, it appears that if I can export a single solid stl with separate regions, then perhaps I can do this without exporting surfaces to stl. Am I right? |
Yes, you are right :)
In geometry definition: Code:
surface_with_regions.stl Code:
surface_with_regions |
