The model contains one varying compartment called c and a species s. The species is not directly affected by anything but the concentration will change as a result of the varying compartment size. However the amount of the species will remain constant.

The model contains one rule:

Type Variable Formula
Rate c 0.5 · c

The initial conditions are as follows:

Value Units
Initial concentration of s 2 mole
Size of compartment c 1 litre

Note: The test data for this model was generated from an analytical solution of the system of equations.
