A Numerical Study of Landau Damping with PETSc-PIC
Daniel S. Finn, Matthew G. Knepley, Joseph V. Pusztay +1
We present a study of the standard plasma physics test, Landau damping, using the Particle-In-Cell (PIC) algorithm. The Landau damping phenomenon consists of the damping of small o…
Finite Element Integration with Quadrature on the GPU
Matthew G. Knepley, Karl Rupp, Andy R. Terrel
We present a novel, quadrature-based finite element integration method for low-order elements on GPUs, using a pattern we call \textit{thread transposition} to avoid reductions whi…
Modeling Charge-Sign Asymmetric Solvation Free Energies With Nonlinear Boundary Conditions
Jaydeep P. Bardhan, Matthew G. Knepley
We show that charge-sign-dependent asymmetric hydration can be modeled accurately using linear Poisson theory but replacing the standard electric-displacement boundary condition wi…
Run-time extensibility and librarization of simulation software
Jed Brown, Matthew G. Knepley, Barry F. Smith
Build-time configuration and environment assumptions are hampering progress and usability in scientific software. That which would be utterly unacceptable in non-scientific softwar…
