What I expected was that the linearUpwind scheme without cellLimited gave me spurious oscillations but it doesn't. The two case (linearUpwind with and without cellLimited) gave me the same results. The localisation of the shock isn't very good compare to …

WebMar 6, 2013 · Prior to this version of OpenFOAM, the form of convective derivative was hard-coded into transport equations. In version 2.2.0, we have introduced a bounded form of discretisation which, when applied to a convective derivative such as fvm::div (phi, h), will include a component for the -fvm::Sp (fvc::div (phi), h) term.
