I have not found the mathematical formula for the "reacf" operator. What is it?
Another issue: When I integrate "Current density norm" = ec.normJ or reacf(V) over an insulating surface, I get a nonzero value, while the integration of "Normal current density = ec.nJ gives zero, as expected.
Hence, I need a manual where all these quantities are explicitly described. I am using Comsol 4.3 and "Electric Currents" module.
