A mass-lumped mixed finite element method for Maxwell's equations. (arXiv:1810.06243v1 [math.NA])
来源于:arXiv
A novel mass-lumping strategy for a mixed finite element approximation of
Maxwell's equations is proposed. On structured orthogonal grids the resulting
method coincides with the spatial discretization of the Yee scheme. The
proposed method, however, generalizes naturally to unstructured grids and
anisotropic materials and thus yields a variational extension of the Yee scheme
for these situations. 查看全文>>
