Defining Functions for FluentDemo2

The IronPython script main.py follows. This script defines all functions executed by the callbacks in the XML extension definition file:

  • The function ImportModel is invoked by the callback <onrefresh> in the step Analysis.

  • The function CreateAnalysis is invoked by the callback <onupdate> in the step Analysis.

  • The function CreateReport is invoked by the callback <onrefresh> in the step Results.
