Many Thanks for your kind reply, I've downloaded netgen v.4.4 and I imported the geometry but while generating the mesh, an error message appears that some libraries are missing. Via IGES, STEP or STL you are able to export to one of the many free preprocessors which can be converted => gmshToFoam, netgenNeutralToFoam ideasUnvToFoam =>unv by salome => Mesh generation with m4/blockMesh, snappyHexMesh, and converters see link mentioned aboveĪnother file-formats that most CAD-programs support are IGES and STEP see=>Salome&Openfoam tutorial "a little bit outdated but you should be able to transfer to actual releases" Otherwise you can use gmsh, netgen, salome, engrid, discretizer calculixs(preprocessor) to name a few programs (all are even for free of charge). Once again, kudos to the CfdOF team for their great work.How to import the CAD drawing into openfoam - CFD Online Discussion Forumsīoth CAD-programms should be able to create STL-files (file_format) to use snappyhexmesh (SHM) The Joko Engineering, Sebastiono Stipa, Evgeniy Ivanov and Tech Bernd channels have some very helpful/insightful OF/CfdOF videos. I'd also like to thank the many FreeCAD YouTubers out there who have created so much excellent FreeCAD content. As a bonus, it supports all the mainstream meshing engines - blockMesh, snappyHexMesh and cfMesh. This somewhat ugly task is greatly simplified in the CfdOF workbench.
Specifically mucking around defining the mesh volume, faces and mesh parameters in dictionary files. The thing I used to hate most about using OpenFOAM was generating the mesh for a simulation. It's the best of both (GUI and manual) worlds. And run simulations manually too, if needed. And yet allows the user to manually edit the simulation files if needed. I love how CfdOF generates the OpenFOAM simulation files, hides most of the complexity and groups most of the common settings into a simple GUI. Yes, OpenFOAM can be used with text files without a GUI but combining the object CAD, meshing and simulation into one GUI based application really streamlines the process. Is it much, much better than running OpenFOAM simulations manually ? Absolutely.ĬfdOF is the GUI that OpenFOAM needs to make it a mainstream CFD tool. CfdOF is a workbench in FreeCAD that allows users to run various OpenFOAM simulations.
OpenFOAM is an excellent tool, but configuring everything via text files gets old, fast. A shout out to the CfdOF developers and supporters for their fantastic work.
