Parameter study

Hi,

Is it possible to set up a parameter study in STKO? Say I have a model which is subjected to a harmonic load with a certain frequency (time series). However, i wish to analyze the same model but I only wish to change the time series. Is it possible to set up such procedures so that several a .mpco-file are generated for each analysis?

Dear Miran,

Parameteric analysis are not built-in in STKO at the moment, though we are currently working on it and it will be available soon.
Now you can achieve the same using some "customCommad" (TCL script) analysis step.
Basically you need to create a TCL script that "opens" the parametric loop, and sets up the parametric objects (in your case the timeSeries and the recorder...).
After that you can add all your regular analysis steps.
Finally you need another simple TCL script that "closes" the parametric loop and wipes the opensees workspace.

Here is an example:
