Mesh Adaptivity

Mike Hackemack: polygons/polyhedral are fun!

Posted on March 15, 2019 by Jean Ragusa

Mike Hackemack (PhD). Mike worked on Sn transport discretizations for arbitrary polygons/polyhedra. We notably extended Adams’ PWLD method to a quadratic serendipity version. Mike also worked on diffusion synthetic acceleration and mesh adaptivity, in direct continuation of the PhD work of Yaqi and Bruno. Mike’s work led to 1 journal publication.

Mike is now staff member at KAPL (naval propulsion lab).

Yaqi Wang: making leaps in radiation transport discretization techniques

Posted on March 15, 2019 by Jean Ragusa

Yaqi Wang (MS+PhD). My first PhD student! Back in 2006, we were among the first ones to do mesh adaptivity for Sn transport on unstructured grids, using high-order finite elements. Whoop!!! In addition, we developed a robust and useful diffusion-preconditioned for transport based on discontinuous finite elements. It is used in several radiation transport codes today. We published a total of 7 journal articles (and numerous conference proceedings).

Yaqi was hired as a staff by INL. He is now the lead architect of their neutronics code, RattleSNake, based on the MOOSE multiphysics platform.
