Thanks John for the message. I am aware of your contribution in that end, however, I was wondering if there was any progress with that class to any other physics problem. However, I would appreciate sharing your code, which (after reviewing to understand more about the class and its implementat

If you don't have a bifurcation you can just write a loop around your solver and ramp up your parameter each "step". John: does the ContinuationSystem offer any advantages in this case? Derek On Mon, Jun 6, 2016 at 11:27 AM John Peterson wrote: > On Fri, Jun 3, 2016 at 1:34 PM, Harriet Li wrot
