FD -DCSD Method for Non-Steady State Form of the Linear Hyperbolic Equation
摘要/Abstract
摘要:
针对非定常一阶线性双曲问题, 采用对时间变量进行差分离散, 而在空间上采用间断流线扩散的方法, 建立了差分间断流线扩散格式 ;并对格式进行了理论分析, 得到了 L∞ ( 0, T;Hr+ 1 (Ω) )模的次最优估计
Abstract:
Through difference for time variable and discontinuous steamline diffusion finite element on space, proposes a finite difference discontinuous streamline diffusion finite element scheme for non- steady state form of the linear hyperbolic equation, and gives a sub-optimal order error estimate in L∞( 0, T; Hr+1(K) ) norm.
