Abstract
Linear hexahedral and tetrahedral elements are joined without linking elements of pyramidal shape. Two triangular faces are constrained by a quadrilateral face in irregular meshes with hanging edges. Edge shape functions are not conforming on the interfaces. Test computations showed good accuracies in the results by the method comparing with results using meshes made of linear hexahedral, tetrahedral and quadratic-nodal-linear-edge elements. The hybrid mesh makes mesh generations flexible and overcomes the degradation of results using the linear tetrahedral edge elements with high aspect ratio for conductive regions in eddy current analyses. The quadratic-nodal-linear-edge elements were also studied and remedy the degradation of linear tetrahedral elements.
