Maxwell 2D (ANSOFT): Error analysis

[Darion13]

Dear all,

I've done many analysis in Maxwell, but in the last ones I'm paying special attention to the error plots. I've been ploting Energy Error and Time Error, but I've got the feeling that I don't know how to properly interpretate it.

Fist of all, to validate one simulation, should I analyse only Energy and Time error? Or are there other solutions that I should watch over?

Second: Does anyone know how to interpretate the magnitud of these errors? A Timer error in any step of 500 is much? An Energy error of 0.325 is much?

Thanks everyone!

Thank you for bringing up the topic of error analysis in Maxwell simulations. I completely understand your concern and the importance of properly interpreting error plots.

To answer your first question, analyzing both Energy and Time error is a good starting point for validating a simulation. However, there are other factors that should also be taken into consideration, such as convergence and accuracy of the solution. It is always recommended to compare the results with experimental or theoretical data, if available, to ensure the accuracy of the simulation.

Regarding your second question, the magnitude of errors can vary depending on the specific simulation and the desired accuracy. In general, a Time error of 500 in a single step may not be significant, but if it accumulates over multiple steps, it can lead to a significant deviation from the actual solution. Similarly, an Energy error of 0.325 may be acceptable for some simulations, but for others, it may indicate a significant deviation from the expected result.

In summary, when interpreting error plots, it is important to consider the specific simulation and the desired accuracy. It is also recommended to compare the results with other sources to validate the simulation. I hope this helps, and if you have any further questions, please do not hesitate to ask.
