Describe your MDO problem in an Excel file

Visualize this study

study = StudyAnalysis("disciplines_spec.xlsx")
if not exists("outputs"):
    mkdir("outputs")

Generate N2 chrt

study.generate_n2(file_path=join("outputs", "n2.png"), save=False, show=True)

Generate XDSM

study.generate_xdsm("outputs")

Out:

<gemseo.core.mdo_scenario.MDOScenario object at 0x7fc2a087e130>

Visualize this study from command line

We can create the same figures using command line inputs:

gemseo-study disciplines_spec.xlsx -o outputs -s '(5,5)' -x -l

where:

• gemseo-study is an executable provided by GEMSEO,

• disciplines_spec.xlsx is the Excel file path,

• -o outputs is the output directory,

• -s '(5,5)' is the size of the N2 chart,

• -x is an option to create of the XDSM,

• -l is an option to create a PDF file with the creation of the XDSM.
