Impetus Advanced

Modeling extreme deformation events such as space debris impact, shaped charge design, warhead fragmentation or hypervelocity in general, is very difficult due to the complexity of the event, which includes non-linear large deformation and short time duration. The IMPETUS ADVANCED module which is part of the IMPETUS Afea Software Suite provides the Next Generation γSPH™ meshless solver to handle these difficult Multiphysics scenarios. The IMPETUS Afea Solver® is a nonlinear transient dynamic explicit Finite Element solver where structural parts can be modeled with advanced higher order elements, the ASET™ family of elements. Coupled with γSPH™ even more challenging engineering problems can be solved. With γSPH™ tensile instability and spurious pressure fields that plagued classic Smoothed Particle Hydrodynamics (SPH) implementations when applied to structural dynamics problems is a thing of the past. The IMPETUS γSPH™ development team has developed a meshless solver that is robust, accurate and easy to use. The γSPH™ Solver takesafull advantage of GPU Technology for parallelization on a single or multiple GPU’s. Fast runtimes with 10’s of millions of particles is computationally efficient because of GPU Technology. The γSPH™ Solver has been proven to be very accurate, matching experimental results! Aligned with the general philosophy of the IMPETUS Afea Solver®, the model set-up for γSPH™ is very simple. A component using the particles can be any geometrical shape and orientation and objects can easily be embedded in the particle domain.
