When analyzing a local distribution such as when analyzing stranded wire AC loss, by dividing the analysis into stages the scale of analysis at each stage can be reduced. With the analysis divided into stages, the whole model geometry can be simplified in the first stage, and a given portion of the model to analyze in detail can be isolated and then analyzed (zooming analysis).
In this document, how to perform multistage analysis using a vector potential boundary condition is presented.
