Limit Result Size🔗

This article outlines various methods for reducing the size of the outcome data in experiments involving lengthy simulations that tend to produce large result data.

Limit result sizes using variable filters🔗

The presentation of results from an experiment can be limited to specific variables by filtering of indicated variables into the result file. This will help to reduce the result file size by including only the desired variables in the results. Filtering works by either selecting a specific View or by entering glob pattern text to find the corresponding variable. Use result filters

  1. Go to the Experiment tab.
  2. Choose the experiment on which to apply the filter.
  3. Click on the Outputs tab.
  4. Add a filter by clicking +New filter.
  5. Choose text or view from the drop-down menu.
  6. When entering text, enter glob pattern text that matches with existing variable paths. Confirm by clicking the checkmark symbol to the right of the text box.

  1. When choosing view, use the drop-down menu in the next field to choose the appropriate view. Confirm by clicking the check symbol.

Modelica models allow hybrid systems that include both continuous and discrete dynamics. By default, models that include discrete dynamics will save the values of variables before and after all events. This means that models discrete dynamics can also produce large result files. Modelon Impact allows this behavior to be disabled such that variable values will only be saved at the indicated frequency specified by the result Interval. In order to turn this off you need to follow the below steps:

  1. Open the settings
  2. Switch to Execution tab
  3. Under SOLVER OPTIONS you see store_event_points
  4. Switch off the option

  1. SAVE the settings

(If the option is not there, click +Add and select it from the list.)
