<div dir="ltr">Hi all<div><br></div><div>I'm trying to find out what is the adaptive controller scheme used in the Runge-Kutta time stepping algorithm. Basically I want to know the function that determines the next time step. I see that the next time step is set with the function TSAdaptChoose(), which calls the pointer function (*choose)() within the structure _TSAdaptOps, but where is this set? <br clear="all"><div><br></div><div>I need to know this for an adjoint analysis to calculate gradients. I was wondering if there is an example of such analysis with the TS structure. I've seen that the RK source file includes a funciton to interpolate the solution, something that is necessary in an adjoint analysis, hence my question about the example. </div><div><br></div><div>Thanks</div><div>Miguel</div>-- <br><div dir="ltr"><font face="verdana, sans-serif"><b>Miguel Angel Salazar de Troya</b></font><span><font color="#888888"><br><font face="arial,helvetica,sans-serif">Graduate Research Assistant<br>Department of Mechanical Science and Engineering<br></font>University of Illinois at Urbana-Champaign<br>(217) 550-2360<br>
