Hello everyone
I am solving an electrostatic problem (with analytical solution) using a finite difference method and I want to plot the error of the FD against the analytical solution.
What would be a good way to measure the error?
I tried the relative and absolute error, but since values range from 0 to high values, these aren't a good measure in all regions.
I'm finding the potential on the outer surface of a group of concentric multi layered spheres caused by a dipole at an arbitrary position inside the inner sphere.
If anyone can point me to the work someone has done before, that would be good enough! Comments and ideas welcome.
Thank you for reading
