摘要
首先介绍p型间断有限元方法,设计求解奇异摄动初值问题的p型间断有限元数值格式.然后算例结果表明,p型间断有限元解的数值通量在节点处具有一致的指数收敛性质.
In this paper the p-version discontinuous Galerkin method was firstly introduced, and the numercial scheme of p-version discontinuous Galerkin method for a singularly perturbed initial value problem is designed. Then numercial results showed that the numerical flux of the p-version discontinuous Galerkin solution at nodes has the uniform exponential rate of convergence property.
