common

Here is where I put model's which are useful across all other models.

cellml/models/common/units.xml
This is my standard dictionary of units. Initially contained only the appropriate units for use with CMISS, but was extended to include some of the common alternative names and units used by models in the repository.
cellml/models/common/reversal_potential.xml
Standard Nernst equlibrium potential calculation, with modifiers. Imports units.xml to define the required units. Defines two components for calculating the Nernst equilibrium potential for one ionic specie or two species, including some extra terms to allow for some of the standard ways the Nernst equation is used in cardiac electrophysiology. This model also defines the gas constant (R) and Faraday's constant (F) values for use in other models.
