The Dedalus Project: A Flexible Approach to Accurately Solving PDEs, with Applications in Stellar Astrophysics | Benjamin Brown, Univ. of Colorado Boulder

Date: 

Friday, March 15, 2019, 1:30pm to 2:30pm

Location: 

Harvard University, Maxwell Dworkin G115, 33 Oxford Street, Cambridge, MA 02138

This talk will begin promptly at 1:30pm. NO REFRESHMENTS WILL BE SERVED.

Abstract: Advances in theoretical astrophysics are powered by computational tools.  Here we discuss the Dedalus project, a flexible, open-source and spectrally accurate framework for solving partial differential equations.  In Dedalus, equations are separated from solution techniques, allowing rapid comparison of different approximations within a consistent numerical framework.  We discuss recent advances in representing spherical geometries and the sparse solution of non-constant coefficient systems, with illustrations drawn from our team's work on stellar astrophysics, convection and magnetic dynamo processes.  Further details are at http://dedalus-project.org/.

Bio: Ben is an Assistant Professor in the Department of Astrophysical and Planetary Sciences at University of Colorado, Boulder.  He received his B.S. in Physics from Harvey Mudd College (2003), his PhD in Astrophysical and Planetary Sciences from CU Boulder (2009).  He is a member of the open-source Dedalus project, and is interested in fluid dynamics, particularly problems arising in stellar and planetary atmospheres and interiors.
