CLEM component

CLEM.ZoneCLEM

The main component to manage a CLEM simulation.

This component is responsible for managing the CLEM model and holds all other components to define a farm. This is a type of APSIM Next Generation Zone and is placed directly below a Simulation component in the simulation tree structure.

The right hand display panel for this component consists of three tabs to show the last CLEM simulation status and messages (Messages tab), the current descriptive summary of the simulation set up (Summary tab) and the entry of parameters for this component (Properties tab). See Summary information.

The following parameters are used to define this component

A single CLEM farm in a simulation may represent a number of farms in a region or village. This is especially important for tracking the movement of resources to and from a shared Market. This parameter provides the multiplier to be used for calculating the amount of resources entering and leaving this farm through the market and therefore accounting for multiple instances of the farm.

Required >0 Default 1 A single farm would use the default value of 1. Old simulation files may have this value set to 0 which will cause a validation error.

This parameter affects which values for crops and forages are selected from the Crop database. They do not need to be different climate regions, but could be different villages within a region. This index can be used in the crop and forage database to list simulation outputs for different climate-soil combinations that can then be selected for CLEM simulations.

This parameter was used in IAT simulations, and may be removed from CLEM in future.

Integer

A full description off all setting in your simulation is a valuable record of a simulation (e.g. for reporting with publications). This switch will determine if this CLEM component will provide it's full summary description in an overall simulation summary description file (HTML format).

The overall simulation summary file will only be provided if at least one CLEM component has this switch on (true)

All CLEM components with this switch turned on will be included in the simulation summary file.

This file (if required) will have the same name as your simulation file with a HTML extension.

We recommend turning this option off to simplify multiple simulations (e.g. experiments and high performance computer runs)

The following parameters are used to help manage Transaction Categories (see link for more details) of all child components

This switch enables the use of the component name as the Transaction Category label.

Setting the Transaction Category of a component to the underscore character "_" will provide a blank entry rather than the component name.

This switch will enable the automatic building of the Transaction Category based on the value determines an upper limit to female breeders where the simulation will stop and report an error. This value is multiplied by the Maximum number of breeders kept to define the critical number and Simulation tree structure. This allows the user to supply the single level category label (or use the component name) and reduces duplication of entering nested level labels.

Blank labels will be ignored

The following parameters define the reporting and calculation of ecological indicators

CLEM will track a range of ecological indicators during the management of pasture (advanced). This parameter is used to define the interval at which these calculations are performed and reported. The default is annual (value of 12) with the month of reporting specified in the property below.

This property is only needed when implementing the Advanced version of Managing pasture but must be set for all simulations. New CLEM components will have a default value of 12.

> 0

CLEM will track a range of ecological indicators during the management of pasture (advanced). This parameter is used to define the end of the first month in which these calculations are performed and reported. The default is July (value of 7) to represent Australian (southern hemisphere), summer pasture growth. The interval of calculation is specified in the property above.

This property is only needed when implementing the Advanced version of Managing pasture

Jan - Dec

The following components are required to set up this component

The Resources holder manages all resources available for the simulation.

The Activities holder manages all activities performed in the simulation.
