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?

Does anyone have any idea of the reason this is happening?
