The goal was simple: create a rapid, hand-calculation method to estimate peak overpressure, impulse, and time of arrival for airblast from high explosives (TNT equivalent). Unlike complex computational fluid dynamics (CFD), Conwep uses empirical curve fits derived from thousands of live-fire tests.
Furthermore, the algorithms used in CONWEP have been integrated into many commercial Finite Element Analysis (FEA) software packages, such as LS-DYNA, AUTODYN, and Abaqus. These commercial tools often include "CONWEP" blast loading features as boundary conditions. However, the integration of these algorithms in commercial software is usually done under specific licensing agreements with the US Government, and the use of these features may still carry specific warnings regarding their application and accuracy limits compared to the official government tool.
