How to run the Rocket Simulation Software

  1. Make sure you have setup the following

    1. Java Version 8
    2. .ork rocket file
    3. .csv flight variables file

  2. Navigate to the file location using the command line

  3. for the next command line input, there are 10 important arguments

    1. jarname.jar - the name of the simulation software jar file
    2. filepath/orkfile.ork - file path to your .ork file that has the rocket configuration
    3. filepath/csvfile.csv - file path to your .csv file that has average flight parameter values
    4. outputpath - the file path to the simulation output file that has a gaussian distribution
    5. numberOfSims - number of simulation you want to run
    6. standardDeviationFromAverage1 - double whole number representing the % away from the average csv value (can leave these at 0 for no variance)
    7. standardDeviationFromAverage2 - etc...
    8. etc...
    9. standardDeviationFromAverage5 - etc...

  4. Type 'java -jar jarname.jar filepath/orkfile.ork filepath/csvfile.csv outputpath numberOfSims -v1 standardDeviationFromAverage1 -v2 standardDeviationFromAverage2 -v3... etc...'

e.g "java -jar SimulationGeneratorExecutable.jar src/main/resources/RocketDesign.ork src/main/resources/dummyData.csv output.csv 10 -v1 2"

FOR TESTING: If you would like to test our program, you can use find the above files in G16RocketMonteCarlo/src/main/resources/

  1. The command line will then output a lot of logging data and finally finish with "successfully written CSV data"
