alimea is on a distinguished road
I want to calculate Nusselt Number by swakFunctions in every point of a patch by this code that is added to "controlDict" file"

type patchExpression;
outputControlMode timeStep;
outputInterval 1;
verbose true;
expression "D*snGrad(T)/(T-T_inf)";
log true;

I think I should change the accumulations from average to the other mode, but I don't know which mode! because it gives me the average of Nusselt around the cylinder!
Could you plz tell me the answer?
