Hello, I have issues with the adaptive time stepping when using theta methods. The time step selected is extremely really small, much smaller than the time step selected by the explicit runge-kutta methods (2 or 3 order of magnitude smaller!).
To try understand what is going on, I would like to have information on what is done for the basic adaptive time stepping (which is the one I started using). Also, any help on what is recommended as time-stepping goes would be great. Thanks, -- Dr. Barbier de Reuille, Pierre Institute of Plant Sciences Altenbergrain 21, CH-3013 Bern, Switzerlandhttp://www.botany.unibe.ch/associated/systemsx/index.php
