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.
