OpenFOAM Architecture Highlights
- Programming language syntax the represents mathematical equations and operators.
 - Runtime selection mechanism.
 - Field algebra with automatic memory management.
 - Face-addressing to handle arbitrary unstructured meshes of any shaped cell.
 
OpenFOAM Numerics Highlights
- Numerical schemes: mapping of NVD/TVD to unstructured meshes, V-limiters, filtered limited schemes, LUST.
 - Pressure-velocity coupling: PIMPLE algorithm, ddtCorr, mesh motion handling.
 - Reconstruction of cell-centre velocities from face fluxes for complex physics and multiphase solvers.
 - Matrix solvers: GAMG solver, DIC smoothing, GAMG pre-conditioning, combined DIC/Gauss-Seidel.
 - MULES algorithm to guarantee boundedness of conservative transport with higher-order schemes.
 - Developed efficient and generalised Lagrangian tracking on arbitrary shaped meshes.
 
OpenFOAM Modelling Highlights
- VOF interface compression modelling using counter-gradient transport.
 - Euler-Euler multiphase flow development for best consistency, boundedness, coupling, conservation, etc.
 - Combustion modelling, including LES variants.
 - Architecture and implementation of single turbulence modelling framework to handle incompressible/compressible and single-/multi-phase flows.
 - Using magnetic pressure in MHD.
