leexit New Member Kevin Join Date: Jun 2013 Posts: 4 Rep Power: 12	Hi, I use Openfoam Version 1.5. I was trying to edit the k-epsilon equation for buoyancy case. Basically I have to add a term on the k equation: mueff/sigmag/rhodi(rho)/di(xj). I got mueff/sigma*rho part, but having some trouble with g and di(rho)/di(xj). I think I have to add a nonscalar variable g in the kEpsilon.C file, but need some help. Can somebody give me some resources to make this work? Thank you in advance. Kevin
