    foamSetupCHT

Description
    This utility sets up a multi-region case using template files for
    material properties, field and system files.

    The utility reads constant/materialProperties to create a regionSolvers list
    and to create region directories containing required files within the 0,
    system and constant directories. The materialProperties file contains mesh
    region names with an associated solver and a material:

    bottomAir
    {
        solver          fluid;
        material        air;
    }

    The case must contain a directory called templates, with e.g. the
    following directories and files:
    + 0
      + fluid: p, p_rgh, U, T, k, omega, epsilon, nut, alphat
      + solid: p, T
    + system
      + fluid: fvSchemes, fvSolution, decomposeParDict
      + solid: fvSchemes, fvSolution, decomposeParDict
    + constant
      + fluid: g
      + solid
    + materials
      + air: radiationProperties, thermophysicalProperties, momentumTransport
      + aluminium: radiationProperties, thermophysicalProperties
      + ...
