Abstract

Most of the approaches to BPM use a fixed grid for the numerical discretization. In our opinion, it should be much more efficient in many cases, to generate a space grid during the simulation, which depends on the geometry of the structure and the actual computed field solution. In general, such adaptive generated grid will be highly nonuniform. As a first step to complete 3D adaptivity, an adaptive discretization of a ID cross section is presented to investigate fundamental mathematical problems.
