November 18, 2014, 22:30	Newtonian Relaxation (Nudging)	#1
lannymac New Member Join Date: Jun 2014 Posts: 2 Rep Power: 0	I'm trying to implement nudging into OF. Nudging is described by: da/dt = G*(anudge - a) where a is the variable you want to nudge, anudge is what you are nudging it towards, and G is an inverse timescale. Right now I'm using bouyantPimpleFoam and I want to nudge U, T, and P (or rho if need be). I'm having a lot of trouble implementing this into the code. Does anyone have any suggestions? Cheers, Landan
