Marcusi - already implemented a nice FEM method for attaining the potential / current density using FEniCS, so that ain't a problem. I find it pretty impressive that you, mikeph, could actually give the right answer there when thinking of the - pretty much opposite scenario. I assume current...

I think you are quite right, mikeph! Just writing it down in mathmode curl(B) = mu_0 J <=> dBz/dy - dBy/dz = mu_0 J_1 dBx/dz - dBz/dx = mu_0 J_2 dBy/dx - dBx/dy = mu_0 J_3 Div(B) = 0 => dBz/dz,dBx/dz,dBy/dz = 0 i.e. and J_3 = 0 yields the two equations dBz/dy = mu_0 J_1 -dBz/dx...

sry if it was unclear. There is 1 cylinder which has a radius = some r. This 1 cylinder is covered 2 places along the z-axis with electrodes which induces a current density with no z-component, J(x,y). Thus, this current density is the same for all z and this is what I want to abuse in my...

Hello people, I am doing some work where I need to look at a simplified situation regarding a conductor for which the conductivity distribution does not change along the z-direction of an infinite cylinder. The distribution itself is not symmetric in any way. Presume 2 infinitely long...
