| + | |||
| + | 1) I have an exam on Monday so I'll be pretty busy until then, but I'd like to start looking for equilibria now/soon. I think that means I need to talk to John G about how to find a good starting point, but maybe other people can help? I also need to get a PACE account, which I think Predrag told me he could help with. | ||
| + | |||
| + | 2) When Channelflow gives output for the findorbit command it produces a bunch of .ff files from the original field (one for each Newton step). I wanted to make sure I understand this right: each of these is the previous field plus the adjustment from the Newton step, right? i.e. it isn't just a .ff file containing the adjustment. This means that if it hasn't converged by the time the program terminates, you can just take the latest output and use it as a new input to keep going, right? //John Hyatt 2009-04-09 13:47// | ||

| + | {{gtspring2009:gibson.png?24}} I am at your disposal: johnfgibson on skype, 617 441-3609 by phone. If you want to | ||
| + | talk during the day and I'm not on skype, send me an email and I'll turn it on. Yes, the unewt3.ff file is the previous field plus the adjustment. It's the current best approximation to the solution. // John Gibson 2009-04-09 15:21 EST// | ||
