Solution of static electric and magnetic problems using the integral definitions of the curl and divergence operators

Numerical methods are described which use a basis consisting of the values of the electric field intensity along each edge of a cell and the values of the magnetic flux density normal to each face of a cell. Definitions of the curl and divergence operators in terms of line and surface integrals respectively, as well as Gauss´ law and Ampere´s law, are used to define mesh and nodal equations for determining the field values within the grid from values specified on the outer boundary. Static electric and magnetic problems are solved as examples
