The model contains one compartment called "compartment". There are two species named S1 and S2 and two parameters named k1 and k2. The model does not contain any reactions. The model contains two rules:

Type Variable Formula
Rate S1 S2 · k1
Algebraic n/a S1 + S2−k2

The initial conditions are as follows:

Value Units
Initial amount of S1 0.5 mole
Initial amount of S2 0.5 mole
Value of parameter k1 1 second-1
Value of parameter k2 1 mole litre-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.
