Visualize this study from command line¶
We can create the same figures using command line inputs:
gemseo-study mdo_study.xlsx -o outputs -h 5 -w 5 -x -p
where gemseo-study
is an executable provided by GEMSEO
and the Excel file path mdo_study.xlsx
is the specification of the MDO study.
Here, we set some options of gemseo-study
:
-o outputs
is the output directory,-h 5
is the height of the N2 chart in inches,-w 5
is the width of the N2 chart in inches,-x
is an option to create of the XDSM (compatible only with the study type ‘mdo’),-p
is an option to create a PDF file with the creation of the XDSM.
