TALK=T;RUN(1,1) DISPLAY The submarine part of a floating body sits in the domain of integration, which extends from the water surface to the bottom. The z coordinate is vertically downwards. The water flows in the positive x-direction around, & under the body. In this first case the flow is treated as incompressible, to contrast with the following case in which compressibility is introduced throughout the domain so as to simulate the surface waves. The model cases are subsequently refined in various ways. The results of the calculations resulting from the inputs in this and subsequent cases in this section, together with background information are in the paper entitled 'The Computation of Flow around Ships with Allowance for Free-Surface and Density-Gradient Effects' by D Brian Spalding in the Proceedings of the First Intercontinental Symposium on Maritime Simulation (June 1985).
