## 5.2. History - Reduce

It is usual to save history data very frequently (the default is every cycle) in order to capture high frequency responses.

If a calculation is run for a large number of cycles the history files can become very large.

This window lets you reduce the size of history files by removing data for some cycles.

  - If you specify a reduction factor of 3, data for two out of every three cycles will be removed from the file.
