How does Comsol compute solutions?

Please login with a confirmed email address before reporting spam

Hi,

I have a model of a thin wire inside a big cylinder and I put an electric potential of -10kV on it. I have plotted a graph of E field normalised against x coordinates (which is in the direction along the wire), and I don't quite understand the solution.

So I was wondering if Comsol takes the values from its surrounding mesh and interpolate to the point where I want? (If so, that's going to be quite a problem as the electric field jumps from 0 to 10^7 and that will affect the results when i take the average)

Otherwise, how does it get the electric field values?

Eunice
