ODE solver not running full time span

I have never encountered this issue before but I am solving a large system with ode15s and have specified a tspan of 0:0.01:360 but the solver is only outputting solutions up to t=321.6. I'm assuming there is a numerical issue but the solver is not outputting any error. Has anyone else experienced this and found a fix?

Show us your code.

That suggests to me that you should have received a warning but perhaps you've suppressed it? Something along the lines of "Failure at t=321.6. Unable to meet integration tolerances without reducing the step size below the smallest value allowed (some_small_number) at time t."

Did you turn warning off in your code or turn off specifically the warning with identifier MATLAB:ode15s:IntegrationTolNotMet?

[Fixed warning identifier to refer to ode15s not ode45.]

[Torsten]

Or you might have defined an event and the code stopped at the time when this event happened ?

[Steven Lord]

That's another possibility, yes.

That was it, the warning was turned off. I don't recall doing this however and didn't even know you could do that. I was working off code by another author edited for my model so it must have been turned off somewhere in there or one of the other codes I was using I suppose. Thanks for the help!
