Run stops after sometime
Closed this issue · 2 comments
After running for sometimes, it stops. What does this error mean? I did not change or replace any file. Just unconstrained J1, J4. Before it was running properly.
[CVODE ERROR] CVode
At t = 86420.3 and h = 0.00145844, the error test failed repeatedly or with |h| = hmin.
time = 86400
ier POST FCVODE()= -3
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
SUNDIALS_ERROR: FCVODE() returned ier = -3
Linear Solver returned ier = 0
time = 86420
Usually, this means a numerical error by the integrator. Most likely a number has become too small or too large in too short a period of time. There is not a lot that can be done, I am afraid. I think it depends on how the values in your system evolve with time, so all I can suggest is look at that. Maybe you can change a bit some of the conditions to get around the issue or stop the model before it crashes.
Ok. Thank you so much.
