hello,

when I am trying to solve the model I am getting the following error when I am using ODE15s as solver.

Derivative of state '1' in block 'XXXX/Integrator Limited1' at time XXXX is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances.

But the errror is resolved if I use ode45 as solver,but there is a huge disturbance in the simulation profile. Is there any way to solve it using ODE15s solver.
