Two dimensional meshes

Fig. A quadrilateral mesh geometrically refined towards inner edges (left), a triangular coarse mesh (middle) and a quadrilateral mesh of a L-shaped domain geometrically refined to the reentrant corner (right).

Three dimensional meshes

Fig. Hexahedral mesh for a Fichera corner geometrically refined towards edges and reentrant corner (left), hexahedral mesh for a thick L-shaped domain without hanging nodes (middle) and with hanging nodes (right).

Magnetic field in a ring with a slit induced by a coil

Fig. Magnetic field in a ring with a large (left) and a tiny (right) slit, induced by a coil, computed by high order FEM for the Maxwell's equations (see Schmidt, K., Sterz, O. and Hiptmair, R. IEEE Trans. Magn. 44: 686-689, 2008.)
