CRD Postdoc Posters Honored at SIAM-CSE Meeting

March 4, 2019


Don Willcox

Two postdoctoral researchers in the Computational Research Division’s Center for Computational Sciences and Engineering (CCSE) won “best poster” during the recent SIAM Computational Science and Engineering (CSE) conference in Spokane, Wash. Don Willcox took the prize for his work as part of the ECP ExaStar project, while Revathi Jambunathan, who joined CCSE March 4 and will be working on the ECP WarpX project, was honored for her Ph.D. thesis work at the University of Illinois at Urbana-Champaign.

Willcox’s poster described SedonaEx, a multi-dimensional, time-dependent Monte Carlo radiation transfer code, which is built on top of the AMReX framework for adaptive mesh refinement. The code is designed to address the three-dimensional, angle-dependent, multi-wavelength radiation transfer problem for astrophysical events such as supernovae. Co-authors on this work include Daniel Kasen, University of California, Berkeley, and Andrew Myers and Weiqun Zhang of Berkeley Lab.

Jambunathan’s poster described her work using a three-dimensional, octree-based multi-GPU code called CHAOS to study the backflow of ion thruster plasma plumes. She performed fully kinetic PIC-DSMC simulations and predict the ion energy distribution in the backflow region for real ion thruster plasma densities.

There were nearly 2,000 attendees at this year’s SIAM-CSE meeting and more than 200 posters. CCSE researchers accounted for at least 18 talks or posters, noted Ann Almgren, group lead for CCSE.
