Abstract
Finite element modelling of geometries with large dimensional differences between adjacent sub-domains or domains which have poor aspect ratios can impose significant demands on meshing algorithms and computational resources. A simple sub-domain scaling technique for electromagnetic analysis of electrical machines by finite element analysis is proposed. The technique can be used to improve aspect ratios and is useful in modelling electrical machines with small air gap lengths.
