User's Manual for EULER3DS

Abstract

EULAR3DS is a robust three dimensional space marching code for computing steady state solutions to the Euler equations applied to external flows. The code solves the integral equations of motion in a finite volume sense and is thus totally conservative. The algorithm used is called the ALPHA-scheme and was developed by the author for this code. This scheme is explicit with either first or second order accuracy and is constructed by splitting the fluxes on cell faces to account for upwind signal propagation. The code solves the governing equations using either a perfect gas model or an equilibrium air gas model due to Srinivasan (Ref. 1). There are six options regarding the grid generation schemes employed and the code is fully compatible with QUICK geometry modelling system. The purpose of this document is to describe the code in a manner that will familiarize the user with the code's options and structure and enable relatively painless usage of the code. Keywords: Shock fitting, External inviscid supersonic flow.
