Hi ,
I want to find the capacitance by solving the Poisson equation. I solved the voltage potential and was able to plot the voltage potential. I want to find the electric potential and energy from from the voltage
First i have to find electric potential which is gradient of voltage.
Then i have to find the energy Energy = integral(1/2 * Epsilon * E^2) over volume.
Can you help me find the gradient of voltage and then the energy ?

If you setup the problem using PDE Toolbox, look here for example, then you get the gradients of the solution in the results.

I don't have good suggestion without knowing what is the required solution. My guess is that you might be encountering under resolved results, try increasing mesh density.
