Critical load combination finder


Determines which load combinations are critical for an already modeled and loaded structure. At the end of the script run the critical load combinations are going to be selected within the analysis settings for further calculations. The script uses the load combinations that were already in the model before execution, no new load combinations are getting created. 

The algorithm is the following:
- Run an analysis for all existing load combinations
- Run a design calculation for all existing load combinations
- Find critical load combinations:
 - Choose a member and find the load combination that caused the highest design utilization for that member
 - If this design utilization is larger, than the set limit (50% by default), then add it to the list of critical load combinations
 - Do this for every member
- Run a quick 1st order static analysis for the critical load combinations only
- End result: the checkboxes for the critical load combinations within the analysis settings will be checked in for further calculations

After the start of the script run, input parameters can be set through a dialogue window, which include the minimum member utilization and some analysis and design settings, since the algorithm is based on design results.
