Advances in HYDRA and its application to National Ignition Facility (NIF) Capsule Designs
Abstract
We will outline new capabilities added to the HYDRA 3-D radiation hydrodynamics code. These include a laser raytrace package, implicit Monte Carlo photonics, and new Arbitrary Lagrange-Eulerian (ALE) grid motion algorithms. We will also outline strategies employed in adapting the code for efficient performance on massively parallel architectures. These improvements enable HYDRA to perform 3 D simulations of an expanded range of ICF targets, including simulations of radiation hydrodynamics in hohlraums. Simulations of multimode hydrodynamic instabilities on ignition capsule designs can now include a broader range of modes (L ~4-120). These enable us to examine the importance of non linear coupling into the lowest mode range. We will present simulations of standard 300 eV NIF capsule designs and new designs driven at a peak temperature of 250 eV.
