The linear hexahedral and tetrahedral elements are joined without linking elements of pyramidal shape. Two triangular faces are constrained by a quadrilateral face in an irregular mesh with hanging edges. The shape functions are not conforming on the interface. However, test computations proved a good accuracy in the results by the method. It makes the mesh generation easier and overcomes the degradation of the accuracy in the results using only the linear tetrahedral elements in eddy current analysis.
