本文提出了一种切比雪夫多区域方法，它可以在区域的无限制四边形剖分上求解守恒型双曲型方程组。在每个子域的解决方案和通量近似交错网格切比雪夫方法。因此，该方法在子域分解方面是非结构化的，但是在子域内是强结构化的。子域之间的通信是由迫击炮的方法在这样一种方式，该方法是全局保守的。该方法适用于线性和非线性测试问题和频谱精度证明。(C)出版社：Academic Press，Inc.
We present a Chebyshev multidomain method that can solve systems of hyperbolic equations in conservation form on an unrestricted quadrilateral subdivision of a domain. Within each subdomain the solutions and fluxes are approximated by a staggered-grid Chebyshev method. Thus, the method is unstructured in terms of the subdomain decomposition, but strongly structured within the subdomains. Communication between subdomains is done by a mortar method in such a way that the method is globally conservative. The method is applied to both linear and nonlinear test problems and spectral accuracy is demonstrated. (C) 1996 Academic Press, Inc.
