ProSAir 2022.11 User Guide

Abstract

ProSAir (PROpagation Of Shocks in AIR) is a finite volume, compressible fluid dynamics solver based on second order MUSCL-Hancock time integration and the AUSMDV hybrid flux vector/difference splitting developed by Wada and Liou. ProSAir’s primary use is for modelling air-blasts in and around structures and estimating the resultant structural loading. ProSAir is a successor to Air3d version 9 and version 2022.11 still uses the same numerical algorithm. ProSAir improves on Air3d by an improved user interface. Key features are: Easy to use CFD modelling of blast waves caused by detonation of a single high explosive device. Fast and robust due to use of the well established AUSMDV finite volume scheme for accurately capturing shocks. Second order accuracy achieved by its MUSCL-Hancock integration scheme. Use of spherical and axi-symmetric calculation phases to reduce run times. Support for running on multi-core/processor computers. Windows XP/Vista/7/8/10 64-bit version supplied as standard; 32-bit version for use on legacy systems is still available. Graphical user interface allowing rapid building of geometric models made up of simple geometrical components. Graphical display of solution during execution. Batch jobs via command line invocation. Window failure model based on the SAFE/SSG Glazing hazard guide Can provide history of pressure, velocity, density and temperature at tens of thousands of target points around the domain. Graphical display may be captured to create video presentations. User guide with many examples including sample input and output files. Restrictions: Explosive charges are assumed ideal, spherical and with no afterburning. No method to input geometry from CAD packages. Flowfield itself cannot be post-processed.
