The Simeo script mode (in java) to run background simulations

The models in Simeo are hosted in modules. When launching Simeo in interactive mode, the user first creates a project and chooses which module he wants to use. An initialization stage follows to build an initial scene (e.g. an empty 100 x 100m scene, or a new scene with plants inside by loading an ops file…) and to set the parameters for the simulation time (e.g. values for coefficients). If the module implements a growth model, it is then possible to trigger an evolution to a given date or time.

It is possible to do the same without any user interaction by writing a java script. Simeo script mode can be useful for long or repetitive tasks: first tune your simulation in interactive mode with few iterations or data, then write the script and launch it on a bigger machine to have results on more iterations or bigger data.

A script example

The Simeo scripts follow the Capsis architecture. Here is an example script to do the following:

  • start an Edito project (Edito is a module of Simeo: the scene editor, no growth capabilities)
  • load an ops file which name was given to the script (parameter 1)
  • set Edito overwrite mode (the original files will be overwritten)
  • send the root scene of the project to the Archimed1 export plugin
  • configure Archimed1 with a given parameter file (parameter 2)
  • run the plugin (will calculate irradiance at the organ level and write the result in new attributes in the original files)

This script may be run on a bigger machine if needed, for example if the scene contains a lot of adult trees with numerous and fine organs, or if Archimed1 is configured to work with a lot of details.

The script

package jeeb.simeo.module.simeoeditor.scripts;
import java.util.List;
import jeeb.simeo.extension.export.archimed1.Archimed1ExportScriptStarter;
import jeeb.simeo.module.simeoeditor.model.EditoInitialParameters;
import jeeb.simeo.module.simeoeditor.model.EditoMockup;
import jeeb.simeo.module.simeoeditor.model.EditoScene;
import capsis.kernel.GScene;
import capsis.kernel.Step;
 * A Simeo script. Loads the given .ops scene file and sends it to the Archimed v1 radiative balance
 * tool.
 * Two ways to launch it:
 * <pre>
 * (1) sh -p script jeeb.simeo.module.simeoeditor.scripts.ScriptTristan2012 
 * (2) java -cp class:ext/* jeeb.simeo.module.simeoeditor.scripts.ScriptTristan2012
 * </pre>
 * See usage () below for expected parameters.

How to launch the script

Open a terminal, change directory to the amapstudio install directory, then type a command like the following (adapt for your ops and Archimed1 configuration file):

sh -p script jeeb.simeo.module.simeoeditor.scripts.ScriptTristan2012 tmp/francois/francois.ops tmp/francois/archimed1.config
