I was wondering how the energy error used for determining convergence is defined in ANSYS Maxwell. My understanding is that, at each iteration, the total field energy from the electric and magnetic field is calculated. This value is then compared to some reference energy value to get the error that determines whether additional adaptive passes are needed. If this is correct, I was wondering where does this reference energy value come from.

Thanks in advance.

I think this can be found in the user manual. Here is the expression for the energy of an electric field:

You can also look up energy expressions for other types of solutions such as magnetostatic etc. in the manual.

Thank you gordon. I found these expressions in the manual, but my question is how the energy error in the convergence process is calculated. What is the reference energy value that the U in the equation above is compared to when we are talking about the energy error.

Well, maybe i'm late, but as i searched for this answer i found this:nAs i understand it, the error energy is the difference between last two total energies. Hopy it helps.n
