User Defined Scalar (UDS) For Electric Potential -- CFD Online Discussion Forums

March 30, 2013, 07:22	User Defined Scalar (UDS) For Electric Potential	#1
A CFD free user Senior Member A-A Azarafza Join Date: Jan 2013 Posts: 226 Rep Power: 14	Hello Folks I want to define two electric and protonic potentials inside a fuel cell using UDS. Here's the problem: when I define electric field, then it's required to define UDS diffusion coefficient which is in fact, electrical conductivity and has a dimension just (1/ohm.m) and it's different from UDS diffusivity coefficient exist in material panel which is (kg/m.s). How can handle this problem? Furthermore, in material panel there are also other parameters such as density or viscosity and etc. what should I do with them for UDS? Should I actually use material panel for this purpose? Please give me some advice. Thank you in advance. __________________ Regard yours Last edited by A CFD free user; March 30, 2013 at 14:08.
