Hi all,
I am relatively new to OpenFOAM, and need some help in creating an stl file with named regions. I am trying to model scalar transport in an arbitrary geometry. For starters, if I had to mesh the region inside a cylinder using snappyHexMesh, with defined inlet, outlet and wall to assign boundary conditions, how should I go about this? Thanks. |

Hi kauraajn,
that's not really rocket science ![]() 1.) Just few examples what's already available: Creating waterproof STL using snappyHexMesh or salome (obligatory to read and to understand) Giving patch names within stl files how to define patches with snappyHexMesh from a STL file ? Patch Names in STL file for snappyHexMesh snappyHexMesh - different patch names from stl file etc. 2.) Check free available OS Software for STL creation and meshing: 'Salome Meca' and 'FreeCAD' 3.) Use exisitng Linux commands to manipulate and check ASCII STL files cat, split, grep, ... 4.) and OpenFOAM utilities https://cfd.direct/openfoam/user-gui...#x14-1090003.6 surfaceAutoPatch, surfaceRefineRedGreen, surfaceCheck, ... 5.) Use 'ParaView' to check your STL geometry 6.) Start with some simple tutorials, e.g. 'motorBike', 'elbow' And let me know if you need more support ... Damian |
