Box 5031, NL-2600 GA Delft, The Netherlands ABSTRACT A finite element package is described for computing stationary and static electric and magnetic fields in inhomogeneous media. A high efficiency and accuracy are obtained by formulating the problem directly in terms of the required field strength. The medium parameters inside the domain of com- putation can be both linear and nonlinear and they may be anisotropic, also. A combination of edge and nodal elements is used for obtaining an accurate expansion of the field strength throughout the domain of compu- tation. This is done such the conditions on internal surfaces of discontinuity in medium parameters, as well as along the outer boundary, can be mod- eled easily. Various post-processing facilities are available for examining the
