一类广义的Lax-Friedrich格式
A Class of Generalization Lax-Friedrichs Schemes
【摘要】 构造了一类计算双曲守恒律初值问题弱解的2N+1点显式格式,该格式是Lax-Friedrich格式的推广,它在CFL条件N的限制下为TVD格式。用该格式进行数值试验,结果令人满意。
【Abstract】 In this paper. we present a class of new frist-order accurate (2N+1)-point explicit schemes for the computation of weak solutions of hyperbolic conservation laws. These schemes are TVD schemes under a CFL-like restriction of N. The numerical solutions obtained in calculation of initial value problem are satisfied.
