Hi,

I am a new user to Open Foam, and I am trying to understand the code in the UEqn.H file in simpleFoam. On line 9, as part of establishing the left-hand side of the U equation, there is the command "+ turbulence->divDevReff(U)". My understand is that the implementation of divDevReff(U) will be selected by the turbulence model choice made in constant/TurbulenceProperties. Several sources (http://openfoamwiki.net/index.php/Bu...DevReff.28U.29, http://www.cfdsupport.com/OpenFOAM-T...t/node209.html), seemed to support this. However, whenever I look in any of the files I have for Open Foam v3.0, I can find no function definition in any of the turbulence models. In fact, the only thing I can find in regards to divDevReff(U) is a series of virtual functions defined in IncompressibleTurbulenceModel.C (http://www.openfoam.com/documentatio...96_source.html). Seeing as how most of the solvers have a line like this, plus the tutorials were working, there is just something about this I'm not getting. Would anyone mind sharing with me how this works, and where the definitions are for divDevReff(U) in the different turbulence classes? Thanks!
