johnwinter Member john Join Date: Nov 2010 Posts: 50 Rep Power: 16	Hi All, I am solving negative ion conc equation (UDSI -0) and potential difference equation (UDSI-1). I have a problem in UDSI-1 source term. The equation is => del^2(phi) = (e/epsilon)UDSI-0 the units are => Volt/m^2 = Volt-m(ions) to make units consistent i devided RHS with C_VOLUME(c,t) hence it beocmes Volt/m^2 = Volt/m^2 but when i devide with cell volume UDSI-1 is diverging. Could you please help me with this problem. Last edited by johnwinter; June 6, 2011 at 04:18.
