The model contains one compartment called C. There are three species called S1, S2 and S3 and two parameters called k1 and k2. Compartment C is 0-dimensional. The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 | k1 · S1 · S2 |
S3 → S1 + S2 | k2 · S3 |
The model contains one event that assigns values to both species S1 and S2:
Trigger | Delay | Assignments | |
Event1 | S1 < 0.45 | 3 | S2 = 1.25 |
S1 = 0.6 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | mole |
Initial amount of S2 | 2.0 | mole |
Initial amount of S3 | 1.0 | mole |
Value of parameter k1 | 0.75 | mole-1 second-1 |
Value of parameter k2 | 0.25 | 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.
