    dimensionedConstants
 
Description
    Dictionary reading and supplying the dimensioned constants used within
    OpenFOAM, particularly for thermodynamics.
 
    The values are read from the OpenFOAM etc/controlDict and should be
    changed to run with a different set of units from the default SI units.
