Hello,<div><br></div><div>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!).</div><div><br></div><div>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.</div><div><br></div><div>Thanks,</div><div><br></div><div><pre class="moz-signature" cols="72">-- </pre><pre class="moz-signature" cols="72">Dr. Barbier de Reuille, Pierre
