DLC Member Davide Lupo Conti Join Date: Nov 2009 Posts: 34 Rep Power: 16	Hello to everyone, I'm working with openFoam 1.5-dev. I'm working on a problem that involves mesh motion. I'm not particulary happy with the mesh diffusivity already implemented, therefore I'm trying to make a new mesh diffusivity, but I got stuck just at the biginning. Can anyone explane me how the quadratic and exponential diffusivity work? I relly can't get further than the line Foam:quadraticDiffusivity:perator()() const { return sqr(basicDiffusivityPtr_->operator()()); } in quadraticDiffusivity.C every suggestion is useful! Thanks Davide
