Description of calculation methods used in VEBE, to determine the effects and consequences of conventional weapons

The VEBE model is made for simulations of military attacks with conventional weapons against urban areas, as well as major civil disasters like blasts and gas explosions. It describes how pressure and fragments act upon buildings (incl. shelters), humans and underground supply systems, how fire is initiated and spread between buildings and finally how the damaged buildings affect humans and shelters. A simulation is performed either with Monte Carlo technique with a statistical result presented after a play with any number of rounds is finished, or it can be performed with one single round with the possibility to watch the process graphically on a computer screen. This report presents a thorough description of the calculation methods used in VEBE.
