The model contains one compartment called "compartment". There are two species named S1 and S2 and two parameters named p1 and p2. The model contains one reaction defined as:

Reaction Rate
S1 → S2 Piecewise(‎‎p1, False‏‏, p2)

The initial conditions are as follows:

Value Units
Initial amount of S1 10 mole
Initial amount of S2 0 mole
Value of parameter p1 1.5 mole second-1
Value of parameter p2 0.05 mole second-1
Volume of compartment "compartment" 1. litre

The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.
