Hi,
I have got a simple problem which makes me struggle.
I have a rectangular thin conductive sheet (2D) of width w, height h
and conductivity suspended in air.
I would like to calculate with COMSOL/Femlab the electrical resistance between one of the corners of the conductive sheet and any other point on the sheet?
I selected the 'conductive media DC' mode in 2D. I am not sure what
boundary condition I should choose and how to apply a potential to one
of the corners.
Since the sheet is suspended in air I thought of putting isolating
boundary conditions on all 4 sides, but then how will I apply the
potential to the corner? Somehow it does not give meaningful results.
Your help is greatly appreciated.
David
