Abstract

The Center for Computational Sciences and Engineering (CCSE) at LBNL is a high-performance modeling and simulation group interested in applications described by complex partial differential equations including fluids (industrial, biological, and micro/nanoscale), plasma physics, microelectronics, and environmental flows. The underlying software framework we develop and use is called AMReX, a GPU/exascale-enabled block-structured adaptive mesh refinement software framework that also includes particle/mesh, embedded boundary, and linear solver capabilities. We also develop data-driven / machine-learning enhancement, and code coupling strategies to both accelerate and increase the fidelity of our codes. We are looking for collaborators with common interests in the computer science, applied mathematics, and/or application science aspects of research performed within CCSE.

Desired Skills

C++, python, numerical methods, partial differential equations, domain knowledge in fluids, plasmas, microelectronics, and/or environmental flow.
