Abstract
The report describes a large-scale medium-resolution computer simulation of blast propagation inside a structure with many compartments, following the explosion of a conventional warhead inside one of the compartments. The simulation is an extension of the quasi-static blast-propagation simulation INBLAST, which is part of the General Vulnerability Assessment Model. In contrast with the 1-D or 0-D former INBLAST, the new simulation uses a 3-D third-order finite-differences scheme and is able to model the shock wave in addition to the quasi-static pressure. The rupture pressures and the systems' vulnerability are computed in a way that is similar to what was done in the former version. Refinements in the modelling of panel response and rupture have been added in order to better utilize the more precise loading characterization of the new CFD algorithm.
