In this paper, a technique of magnetostatic field analysis for structural models with defect of arbitrary inclination angle is presented by adding a function obtained from conformal mapping to the approximate potential function based on the conventional FEM scheme. In this technique, geometry of the defect is not explicitly expressed on the orthogonal grid type FEM mesh but held as function within the analysis program. Since the change of the defect shape is reflected in that function, it becomes possible to use the original mesh without being changed. The magnetic flux density distribution around an inclined defect obtained by this presented technique showed good agreement with that from FEM analysis.
