The model contains one compartment called "compartment". There are three species named S1, S2 and S3 and one parameter named k1. The model contains one reaction defined as:

Reaction Rate
S1 → S2 k1 · S1 · compartment

The model contains one rule:

Type Variable Formula
Rate S3 multiply(0.05, 3)

The model contains one functionDefinition defined as:

Id Arguments Formula
multiply x, y x · y

The initial conditions are as follows:

Value Units
Initial amount of S1 1.5 mole
Initial amount of S2 0 mole
Initial amount of S3 0 mole
Value of parameter k1 0.5 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.
