hi,all

Do you try to compute the gradient of a scalar variable? Now, I use the utility routine GRADS to compute the temperature gradient at a conduction boundary. You know, the heat flux can be compute by the temperature gradient. OK! I acquired the heat flux by the kind of way.

However,a problem is always dazzling me.

Do you try to use "WALL HEAT FLUX" variable name to acquire the heat flux directly?

I try the two kinds ways to compute the wall heat flux, but the results don't coincide, why?

If you are interested in the problem, we can discuss this problem in here!
