i am 3rd year electrical student using comsol 3.2. i am interested in calculating the capacitance of power transmission line. for that i modeled two parallel cylinders having radius 0.1m and length of 4m and put1volt and 0volt respectively and enclosed the whole arrangement in a cube of 10m length. on all six faces of cube i put boundary condition of zero charge/ symmetry . by using sub domain integration of energy density over the domain i found the energy in the surrounding region of two cylinders and by using the formula energy=(C*V^2)/2. but i am not getting the correct value of capacitance. please help to find out the error in my simulation .is their any edge effect. and how to avoid edge effect.
