lowest-order hexahedral Raviart-Thomas finite elements; Convergence; numerical example
Summary: Basic interpolation results are settled for lowest-order hexahedral Raviart-Thomas finite elements. Convergence in H(div) is proved for regular families of asymptotically parallelepiped meshes. The need of the asymptotically parallelepiped assumption is demonstrated with a numerical example.
