CCAPS_vardens

Overview

This is a version of the Cell Centred Approximate Projection Solver CCAPS for the case of incompressible, inviscid, variable-density flow following Bell and Marcus 1992.

This is identical (or at least, was at the time of writing) to the main code running with use_vardens = true.

Generally, the code has been split into different versions because tracking options for the various classes of model equations and extra physics options was becoming unwieldy. Given the point of SimpleCFD, the extra reproduction of core code is acceptable given the gains in clarity, etc.

Specifically, this was split to thin out extraneous options from the existing code before making modifications necessary to tread background state subtracted models.

See the main CCAPS wiki for further information, testing etc.
