hello
when I select 10 year frequency under option and run the system, intensity is correct. However when I run the system for 50 year frequency , the frequency has changed but the intensity is still the same. I have opened the idf file in text to check the accuracy of the values and the idf file is correct. How do I fix it to show the proper intensity.thanks

As I recall, the Frequency from Drainage Options is assigned to the area when it is initially created. If you want to change the Frequency for your areas, run the Drainage>Flows>Bulk Area Update command.
Thanks
