October 9, 2015, 09:41	UDF gradient drop	#1
Bruno Machado Senior Member Bruno Machado Join Date: May 2014 Posts: 271 Rep Power: 13	In my simulations, whenever I set a boundary as a gradient 0 for a UDS, it drops the value of the scalar near the boundary. It looks like it computes the gradient from one point inside the domain I'm solving and one point outside. Does any one face something like that? Could you solve it? Regards
