Abstract
TRANSOM is a multi-block, multi-method Reynolds-averaged Navier Stokes solver being developed at DREA to address problems associated with the flow around ships and submarines. It is multi-block because the flow is divided into several distinct regions. It is multi-method because a different solution method may be used on each of the flow regions. At present two different methods of solution can be chosen: a finite volume solver based on the pseudo-compressibility method; and a finite element solver which uses the penalty function method to determine the pressure. TRANSOM is written in C++ following principles of Object Oriented Programming. This document describes the design of the finite volume pseudo-compressibility flow solver in TRANSOM with emphasis on the class hierarchies used to represent structured blocks, structured matrix solvers, and the pseudo-compressibility solver itself. Two comparison reports describe the overall design of TRANSOM and the design of the finite element solver.
