Dear All,
Iḿ trying to use Comsol to solve the laplace equation within a 3-D space.
This 3D space is limitted by a block of 8000x8000x500um.
The Top-Plane xy,500 should be at ground (V=0V).
The potentials at the side (x,4000,z), (x,-4000,z), (4000,y,z),(-4000,y,z) should form a zero-flux boundary with dV/dn=0.
on the electrodes with diameter D/2 and spacing S there should be a current flowing with dV/dn=i/(pi*(D/2)^2).
I build this within the attached model.
The solver cannot solve this problem. Iḿ getting an error that the threshold is reached.
Could anyone help please?
It is also possible that I did some error within the boundary definition or the choice of the physics.
If there could anyone check I would be really greatful.
kind regards
