solvers: twoLiquidMixingFoam: Removed
Simulating the mixing of two miscible liquids is possible my considering them as different species of a multicomponent fluid. This approach also supports an arbitrary number of liquids. The twoLiquidMixingFoam solver has therefore been removed and its tutorials converted to use the multicomponentFluid solver module.
