Job Description

National Institute of Aerospace (NIA) has immediate openings for postdoctoral Research Scholar positions.


Postdoctoral Research Scholar
Unsteady Simulations with Adaptive Space-Time Unstructured Grids

National Institute of Aerospace (NIA) has an immediate opening for a postdoctoral Research Scholar to work in collaboration with multiple government agencies to conduct research on the topic of unsteady simulations with adaptive space-time unstructured grids. This position requires creative individuals who are willing to continually learn and challenge the status-quo. The successful candidate will develop and implement a non-standard numerical algorithm in NASA’s FUN3D code for unsteady simulations on adaptive grids and perform algorithm development, implementation, and extensive verification and validation studies in a teamwork environment at NASA Langley Research Center. Progress will be published in journal articles and presented at relevant technical meetings.

The successful candidate will work as part of team located in the Computational Aerosciences Branch at NASA Langley Research Center in Hampton Virginia, and will be expected to collaborate across branches, disciplines and government agencies in performance of the work.

Primary Responsibilities:
• Implement/verify/validate a new solver (space-time, implicit gradient, hyperbolic viscous, zero-volume, low-dissipation) with FUN3D code.
• Integrate the solver with an existing grid-adaptation module.
• Develop new algorithms as necessary to successfully construct the new solver and demonstrate it for two-dimensional unsteady simulations on three-dimensional adaptive tetrahedral grids.

Requirements:
• PhD in engineering, computer science, mathematics, physics, or equivalent.
• Knowledge in discretization and solution algorithms for unstructured-grid CFD.
• Advanced programming skills in modern Fortran and/or C++.
• Excellent written and verbal communication skills.
• Demonstrated work in cross functional team environment.

Desired Skills:
• Experience with Linux and Git environment.
• Mathematical skills to analyze numerical algorithms.
