General tree structure
The following tree structure provides the minimum APSIM Next Generation and CLEM model components required to set up a CLEM simulation. This file is available in the CLEM examples folder (CLEMDefault.APSIMX).
APSIM next generation requirements
Simulations component
The top level component of any APSIM Next Generation file is a Simulations component. This holds any number of individual Simulation components that can be run together or individually.
DataStore component
The DataStore component is responsible for managing all data (results) generated by all the individual Simulation components as well as messages and simulation summaries.
Simulation component
The Simulation component defines an individual simulation.
Clock component
The Clock component is used to set the start and end date of the simulation and is required in each Simulation component.
Summaryfile component
The Summaryfile component is used by all models to report messages and errors for display to the user.
CLEM requirements
CLEM component
The top level CLEM component is added under a Simulation component. This component manages the CLEM model.
CLEM events component
A CLEM Events component is required as a child of the APSIM Clock.
Resources Holder
A Resources holder is a CLEM component able to hold and manage all resources needed for the simulation.
Activities Holder
An Activities holder is a CLEM component able to hold and manage all activities needed for the simulation.
Additional folders
Any number of additional CLEM folder components can be added to store report and graph components for the simulation.
