Hi list!<br>
<br>
I have a small problem with running a TS program with -ts_type runge-kutta. It<br>
keeps telling me<br>
<br>
Very small steps: 0.000000<br>
<br>
from the very beginning and never gets anywhere. The programs works fine for<br>
other TS types (well, at least euler, beuler, cn and gl).<br>
<br>
I am out of ideas as to why this happens. I even checked the RK source code.<br>
Any ideas?<br></blockquote><div><br></div><div>Yes, the debugger to look at what happens when it chooses the new timestep. This</div><div>is dependent on parameters you pass in (rk->maxerror, rk->p, ts->max_time).</div>
