Within the macro-directory create (if not already present) a folder called “ Mod”. Supposed your Windows-Login is “ username” the default macro path is %APPDATA%\FreeCAD\ which is usually C:\Users\ username\Appdata\Roaming\FreeCAD. Within FreeCAD, locate the macro path by choosing Edit → Preferences → General → Macro and look for the ”Macro path”. Unpack the downloaded archive on your local hard disk. Download the workbench from github by clicking on the button Clone or Download on the github page (upper right corner) and choosing "Download ZIP". Nevertheless, the information here may still be useful to some. Note: This method is possible but not necessary with the introduction of the Addon Manager. Using the Addon Manager in all systems is the recommended way.ĭuring Google Summer of Code 2016 student Mandeep Singh started work on an improved version ( available here) but that version needs further work before it can be fully integrated in FreeCAD. Once again, kudos to the CfdOF team for their great work.Note: using the "addons-installer" is not recommended any more. 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.
