scaling_mod.f90 ==================== The ``scaling_mod.f90`` specifies the relations between physical and code units. To create it, copy the template file ``microphysics/scaling_mod.f90`` (or copy an existing ``experiments/*/scaling_mod.f90`` file). The contents should be essentially self-explanatory. By choosing three scaling units, for example *length*, *time*, and *mass*, all other units are defined. The three basic units may be expressed in CGS or SI units; both units systems are present in the template file. .. toctree:: :maxdepth: 4
