I am trying to use an ODE solver, however I keep getting the following warning or similar depending on what ODE I use.
Warning: Failure at t=1.411226e+00. Unable to meet integration tolerances
without reducing the step size below the smallest value allowed (3.552714e-15)
at time t.
> In ode15s (line 668)
In AP2016 (line 47)
Would anyone know how I fix this? I am trying to get my script to simulate 0-900 days. It works fine when I am running the script for just 1day.
Thanks in advance

It basically means that you have a singularity.
