PLAXIS LE Python API - How can I change the number of slices in the script?

The script examples can be found in the following directory:

C:\Program Files\Bentley\Geotechnical\PLAXIS LE CONNECT Edition V21\API\docs

In there you can open the file Index.html

Then go to Analysis settings under Sub-Modules: 

plxle.analysis_settings

Then under Classes go to:

ConvergenceSettings

Then on the right side you will see its attributes under ConvergenceSettings and the syntax goes like this: 

num_slices : int, optional

Number of slices. Defaults to 30
