#### First-Principles Molecular Dynamics

This scalable first-principles MD algorithm with O(N) complexity and controllable accuracy is capable of simulating systems that were previously impossible with such accuracy.

#### High-Order Finite Volume Methods

High-resolution finite volume methods are being developed for solving problems in complex phase space geometries, motivated by kinetic models of fusion plasmas.

#### Qbox

LLNL’s version of Qbox, a first-principles molecular dynamics code, will let researchers accurately calculate bigger systems on supercomputers.

#### Improving models of clouds and atmospheric turbulence

With simple mathematical modifications to a common model of clouds and turbulence, LLNL scientists and their collaborators helped minimize nonphysical results.

#### Surveys to understand developer health and happiness

Computer scientist Vanessa Sochat talks to BSSw about a recent effort to survey software developer needs at LLNL.

#### Open source is fueling the future of nuclear physics

Open-source software has played a key role in paving the way for LLNL's ignition breakthrough, and will continue to help push the field forward.
