摘要:We propose a weak Galerkin finite element procedure for time dependent reaction-diffusion equation by using weakly defined gradient operators over discontinuous functions with heterogeneous properties, in which the classical gradient operator is replaced by the discrete weak gradient. Numerical analysis and numerical experiments illustrate and confirm that our new method has effective numerical performances.
