Abstract
Boundary-fitted coordinate transformation broadens the applicability of finite difference methods. But for a large class of geometries, coordinate transformation introduces singularities and increases grid skewness, which results in large error and slow convergence rate. In this paper, we present the results of combining curvilinear coordinate transformation with domain decomposition. The irregular domain is first dissected into subdomains which have smooth curves as their boundaries. Curvilinear coordinate systems are then generated for each subdomain. Each subdomain is mapped onto a processor in the BBN Butterfly computer. All the subdomains are processed in parallel.
