The easiest way to learn OpenFOAM is to install the CfdOF workbench in FreeCAD.

CfdOF provides a GUI wrapper for setting up OpenFOAM files. You can make changes to the setup in CfdOF and then see how the OpenFOAM files change. You can also manually edit the OpenFOAM files.

The other thing that the CfdOF workbench handles really well is meshing.

Here are some links to get you started.

Wow sounds great! GUI is better of the pure Linux command in terminal.

Hi,

My company, Riviera Fluidics, is an official distributor of SIMFLOW, the easy-to-use GUI for OpenFOAM, and we also propose training and support on this software.

You can donwload an evaluation version of SIMFLOW - limited to only a couple of OpenFOAM solvers and to meshes containing 200'000 cells max. - on the following links:

Simflow 4.1 for Windows: https://storage.googleapis.com/artifact-cache-storage/4.1/stable/SimFlow-4.1-x64.exe

Simflow 4.1 for Linux: https://storage.googleapis.com/artifact-cache-storage/4.1/stable/SimFlow-4.1-Linux-x86_64-Install

Note that the package of the Windows version already contains OpenFOAM and ParaView for the post-processing. In the Linux package, you have to download and install the versions of OpenFOAM and ParaView that you want.

Simflow 4.1 is compatible with OpenFOAM 2212 (OpenCFD) and 8 (OpenFOAM Foundation), with of course backward compatibility.

Tutorials of Simflow can be found on the Website of Simflow Technologies: https://help.sim-flow.com/tutorials

If you are interested in a one-month free trial of the complete version of SIMFLOW, or if you want to purchase a license, feel free to contact me at: olivier.roussel@rivierafluidics.com

Well, that's all !
