Abstract :
A three-dimensional SOFT (self-organizing finite-element tessellation) mesh generator, based on self organizing topology-preserving feature maps, is developed for electromagnetic field problems. User-supplied probability function controls density of the graded mesh, and local mesh refinements are easily incorporated. Numerical results show that the SOFT algorithm improves not only mesh quality but also calculation accuracy
