ODEPACK
These Fortran solvers tackle the initial value problem for ODE systems. The collection includes solvers for systems given in both explicit and linearly implicit forms.

Serpentine Wave Propagation
These methods for solving hyperbolic wave propagation problems allow for complex geometries, realistic boundary and interface conditions, and arbitrary heterogeneous material properties.

Quantum Molecular Dynamics
A new algorithm for use with first-principles molecular dynamics codes enables the number of atoms simulated to be proportional to the number of processors available.

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.

Chandrika Kamath honored as 2023 SIAM fellow
The prestigious fellow designation is a lifetime honorific title and honors SIAM members who have made outstanding contributions to fields served by the organization.

Patent for reduced order modeling method boosts lattice design optimization
A new component-wise reduced order modeling method enables high-fidelity lattice design optimization.
