Jb. Davies et Aj. Dean, FINITE-VOLUME WITH NONUNIFORM MESH FOR THE SOLUTION OF MAXWELLS EQUATIONS, IEEE transactions on magnetics, 32(3), 1996, pp. 1417-1420
The constraint of 'regular' elements for 'Finite Volumes' applied to M
axwell's integral equations, has been removed by introducing additiona
l 9-node and 10-node bricks. These form 'glue elements: which allow bi
section of brick dimensions ad lib, leading to non-uniform, unstructur
ed meshing. These bricks also permit first rather than zero)th order b
oundary fitting.
