1OverBlown: A Fluid Flow Solver For Overlapping Grids, Reference Guide, Version 1.0

OverBlown is a program that can be used to solve fluid flow problems on overlapping grids. It is built upon the Overture object-oriented framework. This is the reference guide for OverBlown. This document provides detailed information about the equations, discretizations and algorithms used. Refer to the OverBlown User Guide [10] for an introduction to OverBlown and its capabilities. OverBlown has a number of different algorithms that can be used to solve problems for a range of Mach numbers. The Mach number, M, is the ratio of the flow speed to the speed of sound. In particular there are algorithms suited for incompressible flow, M = 0, (method INS) low Mach number flows, M <:5, (method ASF) moderate Mach numbers:25 < M < 1:0, (method CNS) and high Mach number flows 25 < M, (method CNSCAD). reactive Euler equations in 2D (method CNSGOD). OverBlown can be used to solve problems on moving grids. OverBlown can also be used to solv
