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.
- Imperial College London, Chemical Engineering, 1984 – 1988.
