Evaluation of Unstructured and Overset Grid Methods for Blast Analysis using Loci/BLAST with Emphasis on Urban Environments

The MSU Loci/BLAST CFD code was used to study blast wave interactions with structures for different urban environments. A series of analyses which included single building structures inside of ERDC's Blast Load Simulator (BLS) with different obliquity orientations to the flow direction, two building structures inside the BLS with varying gap distances between the structures, and open air blast simulations with four structure scenarios at different building spacings and different blast orientations were performed. Unstructured and overset grid techniques were used during the modeling process and were compared for consistency with shock physics and computational performance. Results show Loci/BLAST's capability to accurately model blast wave interactions in urban environments for both unstructured and overset grids.
