Hi
I am wondering if there is anyone who knows the mathematical fumulation of fac::grad(Us) and fac::div(Us) in openfoam1.6ext? Thanks 
Search for the thesis by Zeljko Tukovic from Uni Zagreb  this is his work and his Thesis and papers (Computers and Fluids 2013) explain it all.
BTW, this is a top5 paper on downloads from Computers and Fluids at the moment! :) Hrv

Thank you for your reply. Wasn't his thesis written in Croatian? As for the paper, Do you mean the one named 'A moving mesh finite volume interface tracking method for surface tension dominated interfacial fluid flow'? Regards Yu

Could you tell me where did he get the equation about the relationship of the pressure and the velocity at the freesurface? Thanks
