- Abstract
- We present a new family of mimetic methods on unstructured polygonal meshes for
the diffusion problem in primal form for solution with regularity C®() for any integer ® ¸ 0.
These methods are derived from a local consistency condition that is exact for polynomials
of degree m = ® + 1. The degrees of freedom are (a) solution and derivative values of
various degree at the mesh vertices and (b) solution moments inside polygons. Theoretical
results concerning the convergence of the method are briefly summarized and an optimal
error estimate is given in a mesh-dependent norm that mimics the energy norm. Numerical
experiments confirm the convergence rate that is expected from the theory (literal)
