Hi Foamers,

I would like to implement a coupled solution of the turbulence equations in foam-extend-3.1. There is already implemented a library which handles the the block matrix. The solved pUCoupledFoam solved the Navier-Stokes equations in their pressure-based coupled form. It saves a lot of computational times and enables openFoam to handle a huge number of mesh elements as well. The next step is to "couple" the turbulence equations.

The steps are the following:

1) copy the library of some RANS turbulence model (for example k Epsilon)
2) change the implementation of the two equations in the kEpsilon.C file in order to get a coupled solutions of these two equations.

Has anyone some suggestions how can I accomplish the second step?
