Hi all,

I would like to know what is the difference between 'upwind' and 'linearUpwind' in the OpenFoam finite volume scheme.

Thank you,

Upwind is your standard 1st order upwind scheme.

linearUpwind is a 2nd order scheme, essentially a Taylor series expansion about the cell center requiring gradient information (hence, the 2nd order accuracy).
