I got a little more curious about simpleFoam. (opens the original)
Read excerpt
I know, OpenFOAM comes with a ridiculous number of solvers (approximately 80 on my last count!).It’s mainly due to the separation of the physics they are each designed to solve.Whilst this means mental-overload for me and you, it’s not all bad.Especially when you get to grips with how a solver like simpleFoam actually works.Finally understand what happens with your initial values during calculationResolve and trouble-shoot solver crashes and errorsControl the computation per time stepCustomise t
