Research
- Theoretical continuum dynamics
- Modern hydrodynamic theory
- Materials modeling
- Global climate modeling
- Numerical algorithm development
- Large-scale computational simulations
There is an emphasis on developing advanced numerical methods for continuum dynamics at all flow velocities and strain rates, and coupling these methods to constitutive models for solid material response and other physical processes such as
- Turbulence
- Chemical reactions
- Combustion
- Phase change
- Heat and mass transfer
- Plasma behavior
Codes
- CartaBlanca: A multi-velocity code for fluid-structure interactions using unstructured meshes and Lagrangian material points.
-
CICE: A computationally efficient model for simulating the growth, melting, and movement of polar sea ice, used to inform long and short-term climate projections. Maintained by the CICE Consortium.
- E3SM: The DOE’s Energy Exascale Earth System model contains LANL-developed ocean (MPAS-O), sea ice (MPAS-SI) and land ice (MPAS-LI) components. that are built using the MPAS (Model for Prediction Across Scales) software framework.
- FEARCE: Fast, easy, accurate and robust continuum engineering model computes processes in internal combustion engines to aid enhanced fuel efficiency and reduced emissions.
-
Icepack: A submodule of CICE that contains all of the sea ice column physics and can also be independently run. Maintained by the CICE consortium.
- Tusas: A general flexible code for solving coupled systems of nonlinear partial differential equations, originally developed for phase-field simulation of solidification.
