Questions about traction-perturbation

Hi Brad.

In this picture, we can change the rate-start-time to control when the traction changes, and I want to know how to control the ending time.
For example, in a total of 30 days, I just want the traction of the first 20 days to change at a constant rate.
Thank you.

This information is for PyLith v2.2.2.

The rate of change is for a constant rate with an initial starting time. If you want a more complicated time history use the th_change See equation 6.1 in section 6.2.
