OpenFOAM is a freely available open-source CFD software and is being widely used in academia and industry. The software has huge potential with many solvers and utilities for pre- and post-processing. On the downside, OpenFOAM has limited documentation and hence with proper training and practice it is possible to leverage its full potential leading to cost-effective, robust and reliable simulation. In this session the participant will be given full exposure to basics of CFD (Meshing, material properties, models, discretization schemes, solver settings, boundary conditions, solution convergence, post-processing…) and how these are implemented in OpenFOAM. Thereafter, hands on training will be provided on a simple CHT case involving solver set-up and post-processing
