Calculate electrical current

Please login with a confirmed email address before reporting spam

Hello,

I want to calculate the electrical resistance of sphere with to contact surfaces in first one i impose potential condition in the seconde one a nul potential and electrical insulation for all the sphere surface.

For calculating the electrical resistance of sphere i calculate the electrical current throught the first surface (inlet) by using the Integration Coupling Variables (I1=Jx*nx+Jy*ny+Jz*nz) and the same expression for the seconde surface (outlet) (I1=Jx*nx+Jy*ny+Jz*nz). In the ideal case i must obtain the same current I1=I2 but the result is differente.

I dont now who to do this modelling in comsol.

Thank for you answer

Hi,

I have raised exactly the same issue in a different geometry. Can someone throw light on this ?
