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 element flow solver in TRANSOM with emphasis on the class hierarchies used to represent elements finite element grids, degrees of freedom, and the solver itself. Two companion reports describe the overall design of TRANSOM and the design of the pseudo-compressibility solver.
