- Hi there,
- I just got the news here, so I don't if I can post, and, if I can, whether my question
- has already been asked.
-
- Anyway,
-
- I'm studying different methods to automatically change the size of a time step
- when solving a time-dependant ODE. Automatically means that the code should
- know when it has to use a larger or smaller time step,
- according to what happens to the sytem.
-
- I'm interested in this problem for a general ODE first. I'd like to see
- all that can be done , to be able to choose, then, which method is the most adapted
- to my specific problem which is a stiff ODE.
- Actually, it's a parabolic PDE (neutronic diffusion equations) on which
- we apply finite volumes (or finite differences) to end up
- with a time dependant system of ODE.
-
-
- I'm interested in getting some references in the litterature.
- I haven't heard on any book dealing with this problem (but I haven't looked
- very hard) ; is there any ?
-
- Thanks in advamce for answering,
- Phil.
