Abstract

The laws that govern natural systems can often be modelled mathematically using partial differential equations (PDEs). Usually the resultant PDEs are not solvable analytically, leaving numerical solutions as the only recourse to gain useful insights into such systems. As a result, it is important to efficiently calculate numerical solutions of PDEs to further our understanding of such systems. In this paper we briefly describe the design and validation of SARAS, a general-purpose PDE solver based on finite difference method (Anderson, 1995; Ferziger & Peric, 2001).
