I am new to paraFoam and was wondering if I could get some pointers on what I need in order to make snappyhexmesh run effectively on an STL file that I brought over from solidworks. I guess I am mainly having trouble figuring out how to effectively refine the mesh around the propeller.

You're not giving much for details, but when I exported an STL model from SolidWorks I had to change some default settings:

Normally CAD programs use measures in "mm" but OpenFOAM reads them as "m" so you have to convert your stl file.
You can do that with "admesh" or after meshing with "transformPoints". If you dont know what you can do else just check this tutorials about snappyHexMesh http://www.holzmann-cfd.de/index.php/tutorial because the OpenFOAM snappy tutorials have some more advanced meshing options and are not so trivial to understand and to use afterwards for your own case. More information would be very helpful Greetings |
