The model contains one compartment called "compartment". There are three species named S1, S2 and S3 and two parameters named k1 and k2. The model contains one reaction defined as:

Reaction Rate
S1 → S2 compartment · k2 · S

The model contains one rule:

Type Variable Formula
Assignment S3 multiply(k1, S1)

The model contains one functionDefinition defined as:

Id Arguments Formula
multiply x, y x · y

Note that in this case the initial value of the species S3 is not explicitly declared and must be calculated by the AssignmentRule.

The initial conditions are as follows:

Value Units
Initial amount of S1 1 mole
Initial amount of S2 0.5 mole
Initial amount of S3 undeclared mole
Value of parameter k1 1.5 dimensionless
Value of parameter k2 5 second-1
Volume of compartment "compartment" 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.
