Adding a modified turbulence model to OpenFOAM v2012

Tim_ · January 15, 2024, 11:58

I am wanting to modify the existing LES turbulence model, Keqn, and have the modified version as a new selectable model when running my simulation (e.g. myKeqn). I understood how to do this in the older versions of open foam (e.g v2.4.0) by compiling it with a makefile and options files. However since the file structure has seemingly changed for OpenFOAM v2012 I am unsure of the best way to go about this.

I have tried adding the modified model using the makeLES function in a make turbulence transport models file to no great success. From what I can understand this all relates to there now being a base class template and potentially the syntax? (but i could very well be mistaken!)

I apologies if this has already been covered and would appreciate being pointed in the right direction.

Hi,
Recently I implemented a modified RANS model in v2112 following this reference. I think it should work for you too.
