Impetus Defense

Modeling Buried Mine Blast events such as Improvised Explosive Devices (IED’s) is very difficult due to complexity of the event, including non-linear large deformation and short time duration. This is why the Next Generation Solver, the IMPETUS Afea Solver® has the module IMPETUS DEFENSE where a Discrete Particle Method (iDPM) is implemented to simulate the soil, High Explosive (HE) and air with discrete particles. The basis for the DPM approach is centered around the fact that soil under blast loading is NOT a continuum and each Discrete Particle represent thousands of soil grains. The soil and HE are treated for what they are – loading mechanisms to the structure in question. The iDPM algorithm takes full advantage of GPU Technology for parallelization, making it computationally very efficient resulting in fast run times.
