Simulation error while integrating a DE like dy/dt = 1/y.

1 view (last 30 days)
Hello,
I've got a DE where there for example dy = 1/y. Because my initial value equals zero, 1/0 equals infinite. Simulink gives an error and tells me that:
Derivative of state '1' in block 'Simulatie_van_Wijk_nieuw/Inertia centrifugal pump/Integrator' at time 0.0 is not finite.
Can somebody help me with this problem (what can I do to work around this?) I still need my DE solved..

As you had mentioned, Simulink is expected to give an error for 1/0.
As a workaround, you can try using 0+eps instead of 0 as the initial condition.
For more details about eps, refer the documentation link :
