PROCESSES INVOLVED IN CFD :
When applying a CFD package to undertake a flow and thermal analysis, there are numbers of steps that involved for completing the CFD Process.
Defining the geometry and domain
Selecting physical sub models
Specifying boundary condition at the frontiers of the domains including walls, inlets, openings, supply fans, exhaust fans jet fans and fire location and burning material properties.
Discretizing the mathematical equations, which includes creating a mesh (which sub-divides the spaces into small volumes), setting time steps (which divides the time into discrete steps) and selecting numerical sub-models
Monitoring the interactive solution process
Analysing the solution obtained
