Compatible Relaxation Based Geometric-Algebraic Multigrid
04 Feb 2016 | | Contributor(s):: Fei Cao
We develop compatible relaxation algorithms for smoothed aggregation-based multigrid coarsening. In the proposed method, we use the geometry of the given discrete problem on the finest level to coarsen the system together with compatible relaxation to from the sparsity structure of the...

On the Preconditioning of a High-Order RDG-based All-Speed Navier-Stokes Solver
04 Feb 2016 | | Contributor(s):: Brian Weston
We investigate the preconditioning of an all-speed Navier-Stokes solver, based on the orthogonal-basis Reconstructed Discontinuous Galerkin (RDG) space discretization, and integrated using a high-order fully-implicit time discretization method. The work is motivated by applications in Additive...

[Illinois] Molecular modeling of structure and salt-responsive morphology of polyelectrolyte-based materials
11 Dec 2015 | | Contributor(s):: Yaroslava G Yingling
In this talk, I will illustrate our recent progress in prediction of responsive morphologies of polyelectrolytes on the example of DNA- based materials. we used atomistic molecular dynamics simulations to determine the sequence, length, and solvent contributions on the persistence length of...
