1. Run a solution with different values

In the previous section you learned how to use ModelSolutions, now we'll see how to execute one ModelSolution multiple times changing some variables via SimulationProject.

 

In the first task for creating a project we will use the following approach:

- we define each run and its parameters in a file (in our case a text file).

- then we configure a SimulationProject to read this file as an <interface> and <resource>

- the resource id names in the SimulationProject must match the name of the variables in the target ModelSolution

- then they can be executed together, with either a unittest or java application:

 

package net.simplace.sim.runs.training.WorkingWithProjects;

 

import net.simplace.sim.runs.ModulesStandardRun;

 

public class Run_01_Project_DifferentValues extends ModulesStandardRun

{

  public static void main(String[] args)

   {

 String tSolutionFileName = "${_WORKDIR_}/training/solution/2_WorkingWithProjects/01_DifferentValues.sol.xml";

 String tProjectFileName = "${_WORKDIR_}/training/project/Project1.proj.xml";

 

 setUp();

 

 showMessage("Starting: Simple Project.");

 runSimulation(tSolutionFileName, tProjectFileName);

 showMessage("Finished Run: Simple Project.");

 

      exit();

   }

}

 

Note that now we provide both the names of the ModelSolution and SimulationProject in the command runSimulation(tSolutionFileName, tProjectFileName);

Task 1.1 Run solution simplace_modules/test/training/solution/2_WorkingWithProjects/01_DifferentValues.sol.xml with 4 different values of STTIME, DOYEM, IRRIGF and WSO, which are defined in simplace_modules/test/training/data/lintul2/runs.txt.

 

 - Create a SimulationProject XML file with two interfaces (one for the project data file runs.txt and one for output files).

         <filename>${_WORKDIR_}/training/data/lintul2/runs.txt</filename>

 

 - Add a resource with all variables that are used in the file runs.txt.

         <resource id="projectdata" interface="projectdatafile">

                      <header>

                <var id="projectid" datatype="CHAR" key="projectid" />

                <var id="simulationname" datatype="CHAR" key="simulationname" />

                <var id="vLocation" datatype="CHAR" />

                <var id="startdate" datatype="DATE" />

                <var id="enddate" datatype="DATE" />

                <var id="vSTTIME" datatype="INT" />

                <var id="vDOYEM" datatype="INT" />

                <var id="vIRRIGF" datatype="DOUBLE" />

                <var id="vControlWSO" datatype="DOUBLE" />

              </header>

            </resource>

 

    - At the beginning of the variable declaration(creation) section also add two variables with keys(one for projectid and one for simulationname, see above).

 

 Hints

      - Put all variables in between <projects><resource><header>...</header></resource></projects> tags.

   - Variable for the projectid would look like <var id="projectid" datatype="CHAR" key="projectid">

 

 Solution

      Open the simplace_modules/test/training/project/Project1.proj.xml to see how it should be done.

Task 1.2 Create a JUnit test using the simplace_modules/test/training/solution/2_WorkingWithProjects/01_DifferentValues.sol.xml solution and

 simplace_modules/test/training/project/Project1.proj.xml

 

 Run created test to see the results.

 

 Hints

   - Initialize new variable, e.g.: String tProjectFileName = "${_WORKDIR_}/training/project/Project1.proj.xml";

   - Dont forget to prescribe the tProjectFileName

 

 Solution

      Open simplace_modules\unittest\net\simplace\sim\tests\training\RunProj.java to see how it should be done.
