Python scripting in Delta Shell
Hidde Elzinga David Rodríguez Aguilera

2. Goals of this workshop
•Why would you like to use scripting?
•What can be done (better) with scripting?
•Which tools are available for scripting in Delta Shell (DS)?
•How could I live until now without scripting…?

3. How?
Introduction:
•DS + Plugins
•Goals scripting (advantages) What can you do with scripting? How difficult is scripting and can you (and we) make your life easier with scripting? Command line scripting Overview of the workshop exercises:

5. Delta Shell: without scripting

6. Delta Shell: Is scripting only much faster?

7. Delta Shell: Is scripting only much faster?

8. Delta Shell: scripting is faster AND more effective

9. Delta Shell: scripting is faster AND more effective

11. What can you use scripting with IronPython for?
Simple (but important!) repetitive tasks
Create new complex functionalities

12. How difficult is scripting?

13. Scripts can also be run from the command line
No GUI commands in scripts can be run in command line

14. •Run SOBEK model
•Import measured data
•Get results
•Plot model results vs data
•Enhance charts
•Use objects to calibrate model
•Calibrate a model
•Plot calibration results
•Choose best fit
•Save results as data (spreadsheets) or graphs (images)
Create SOBEK model:
•Create a SOBEK 3 flow model
•Import branches
•Import cross sections

•Adjust roughness
•Set initial conditions
•Space and time discretization
