Hi,
While I was running a simulation in a model I developed in Simbiology, I recieved the following error:
CVODES returned -4 from module CODES function CVode: At t = 3.63e+06 and h 0 2.2e-06, the corrector convergence test failed repeatedly or with h = hmin
I am beginner in Simbiology. Could you please help to figure our the solution?
Thanks

See the error flags in the CVODE documentation:
https://sundials.readthedocs.io/en/latest/cvode/Constants_link.html#
without the model it is difficulT to help. For start try with decreasing/increasing of the tolerances or use another solver, e.g. ode15s.
