Multi-physics simulation tools for High Energy Density Physics (HEDP) and weapons- relevant applications for DOE and DoD.
Objective: Multi-physics simulation tools for High Energy Density Physics (HEDP) and weapons- relevant applications for DOE and DoD.
The Multi-physics on Advanced Platforms Project (MAPP) is developing next generation multi- physics codes for simulating high-energy-density and focused physics experiments driven by high- explosive, magnetic or laser-based energy sources as well as weapons- relevant simulations. The MAPP approach includes a modular CS infrastructure that serves as the basis of multiple codes, as well as an emphasis on high-order algorithms that are expected to scale better on anticipated architectures.
