Does applying symmetry BC in 3D geometry need spatial care?

Please login with a confirmed email address before reporting spam

Hello,

I have some uncertainty wish to seek for your opinion
.
I am simulating current evolving through a cylinder, in a 3D Cartesian coordinate geometry. I applied the symmetry boundary condition on half of the cylinder. I wonder that if will COMSOL take care of that and calculate the current on the whole cylinder or should I multiply the obtaining current by two?

Thank you
Mahdieh

Hi,

the total current will be calculated on half the cylinder, so you
must multply with two if you have symmetric boundary conditions
