flow-over-heated-plate: Remove unnecessary parameter

[BenjaminRodenberg]

See #226 (comment): From my current perspective, we do not need nMoles.

[BenjaminRodenberg]

I also removed nMoles in the cases flow-over-heated-plate-steady-state and flow-over-heated-plate-nearest-projection, but did not check any results.

Have you also tried this with different OpenFOAM versions? I can imagine that this was there for technical reasons, even if not used. But most probably this originates from the very first prototypes, which were probably also based on something else (as is common in OpenFOAM).

Of course, not 😏

@BenjaminRodenberg Don't forget the changelog entry.

[MakisH]

Indeed. From the OpenFOAM 8 docs:

nMoles: number of moles of component. This entry is only used for combustion modelling based on regress variable with a homogeneous mixture of reactants; otherwise it is set to 1.

This looks correct. From the OpenFOAM.org user guide:

nMoles: number of moles of component. This entry is only used for combustion modelling based on regress variable with a homogeneous mixture of reactants; otherwise it is set to 1.
