The model contains one compartment called "compartment". There are two species named S1 and S2 and one parameter named k1. Compartment "compartment" is 0-dimensional. Species S2 is labeled as an SBML boundary species. The model contains one reaction defined as:

Reaction Rate
S1 → S2 k1 · S1

The initial conditions are as follows:

Value Units
Initial amount of S1 1.5 × 10−1 mole
Initial amount of S2 0 mole
Value of parameter k1 1.023 second-1

In this example the compartment has its spatialDimensions attribute set to zero; i.e., it represents a point and therefore cannot have size or units. The species values must be treated as amounts and not concentrations.

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