Los Alamos National Laboratory Continuum Solid Mechanics Computational Scientist 3 (Scientist 3) in Los Alamos, New Mexico

What You Will Do_

The Methods and Algorithms Group (XCP-4) of the Computational Physics Division at Los Alamos National Laboratory is seeking outstanding candidates for positions at the Scientist 3 level in the area of continuum solid mechanics modeling. The successful candidates are expected to provide direction, work in a team environment, implement, test and verify their models and algorithms in large production software and publish their research in leading scientific journals.

XCP-4 is a group of about 20 scientists with various technical backgrounds doing cutting edge research in advanced computational methods and algorithms for multi-physics applications in support of national and global security. Specifically, we develop state-of-the art numerical methods for shock hydrodynamics and multiphase flow in both Eulerian and Lagrangian frameworks, as well as advanced physics-based computational models in a variety of areas, including high explosives, turbulent reactive flow, and continuum solid mechanics. Our staff provide expertise in these areas through multidisciplinary interactions on teams seeking to provide solutions for large multi-physics codes. Our work supports a variety of Laboratory missions, including stockpile stewardship, nonproliferation, threat reduction, and energy and environmental sciences.

What You Need

Minimum Job Requirements:

  • Expertise in continuum-level modeling of polycrystalline materials under dynamic (shock) loading, including strength and damage behavior, and high-order numerical methods and algorithms associated with it, especially with respect to Lagrangian and/or Eulerian frameworks

  • Ability to obtain a Q Clearance, which usually requires US Citizenship

Desired Skills:

  • Experience with continuum-level modeling of the behavior of multiphase and/or composite materials, especially under dynamic loading conditions

  • Understanding of atomic-level/microscopic physics leading to material behavior, such as crystal plasticity, and creation of sub-grid models or other techniques of mapping these types of models up to the continuum level

  • Experience in developing accurate and robust numerical methods for multi-physics simulation software at the continuum scale using finite- volume and/or finite element methods

  • Experience with theoretical model development

  • Experience in Verification and Validation techniques
