tjliang Member Peng Liang Join Date: Mar 2014 Posts: 59 Rep Power: 12	Hello Foamers, I am doing a multiphase case. I need to differentiate anode interface and cathode interface with gas by judging the directions of electric current density vector. That is to say, if electric current vector flow inward at interface of two phase into electrode then it is cathode, otherwise it is anode surface. Can anyone give me a hint how I can check if the currents flow into or out of the phase interface? Thanks. Bests, Peng
