Los Alamos National Laboratory Verification and Validation Postdoc in Los Alamos, New Mexico
Vacancy Name: IRC74644
Job Title Verification and Validation Postdoc
Location Los Alamos, NM, US
Organization Name XCP-8/Verification And Analysis
What You Will Do
The Computational Physics: Verification & Analysis group (XCP-8) at the Los Alamos National Laboratory (LANL) has an opening for doctoral-level career scientists/engineers with research interests and experience in the areas of code and solution verification, and validation assessments of models with computer codes. Our wide-ranging areas of interest include (but are not limited to) hydrodynamics, solid mechanics, material strength and damage, equation of state, reactive flow, high-energy-density physics, instabilities and turbulence, and radiation transport. We encourage mentoring for new staff to build skills quickly and continued publications/research are prized as well.
The selected candidate will be part of a multi-disciplinary team to assess the effect of numerical error, experimental error, and/or model insufficiency on simulation uncertainty in large-scale physics simulations. This requires assessing the quality of numerical algorithms and physical models that are implemented in multi-physics simulation codes developed at LANL to ensure the veracity of physical predictions involving complex systems. This involves collaborating with code developers, experimentalists, and other physics subject-matter experts in order to understand various errors associated with single physics sub-models and how these affect complex multi-physics simulation results. The successful candidate will evaluate whether numerical algorithms and/or physical models were implemented correctly in LANL codes, and quantitatively determine how well those implementations reproduce representative analytic solutions and/or experimental results. Where appropriate, the candidate will evaluate potential model insufficiencies, as well as evaluate the effect of coupling between physics sub-models on the overall model accuracy. The successful applicant should have a strong background in experimental science, engineering, mathematical or computational physics, or statistics. Experience with interpreted languages such as Python, Matlab, R or something similar is required, Python experience being the most desirable.
We seek individuals who will contribute to the assessment of the quality of models as implemented in multi-physics computer simulation codes. The purpose of these assessments is to provide a basis for confidence in simulation predictions of complex systems. VVUQ assessments evaluate whether the model was implemented correctly in the code, how well the implementation recovers the expected solution—including uncertainties, and bounds of applicability of the implemented model through comparison with experimental results. Quantitative assessments are made to provide a basis for model confidence. Where appropriate, evaluations of incompleteness in a given model are made. Effects of coupling of sub-models on overall model accuracy, precision and bounds of utility are also evaluated.
As these assessments require a broad diversity of technical capability, teaming is essential. Individuals will consult with modelers, code-developers and experimentalists in order to provide high quality assessments.
