摘要
讨论了如何利用间断有限元(DG)法求解一维不定常对流扩散问题,并采用一组特定的数值迹,对该种方法所求解的存在性及唯一性进行了论证,证明了利用间断有限元法求解一维不定常对流扩散问题的解是存在并且唯一的.
A Discontinuous Galerkin Method is discussed for solving unsteady convection diffusion equation, also the existence and uniquencess of the DG solution. To prove the existence and uniquencess of the DG solution, some special numerical traces are chosen, using the numerical traces, to prove the existence and uniquencess of the DG solution.
