A surface panel method runs in parallel across variable sized square arrays of transputers. A geometric parallelism is used for both the data distribution and the algorithm. A flexible geometry definition allows complex three-dimensional surfaces and multiple body problems to be solved. Each body surface is sub-divided into quadrilateral panels. A fast parallel block-iterative solver allows rapid solution of the dense but diagonally dominant linear system of equations. The parallel performance of the surface panel code is described, and the necessary scaling of number of transputers and distributed memory per transputer to obtain solutions of surface panelproblems of order of 10 000 panels is given. As an example, the code is applied to predict ship-rudder-propeller interaction.
