Error when running simple voltage converter in simulink

Hi,

I got this error when when I tried to simulate the circuit: An error occurred while running the simulation and the simulation was terminated

Caused by:

• Solver encountered an error while simulating model 'Teste_Quadratic_boost' at time 5.9442244214857332e-09 and cannot continue. Please check the model for errors.
• Solver could not solve the system of algebraic equations because a singular iteration matrix was encountered. Consider providing more accurate initial conditions. If the problem persists, check the model structure and values of parameters.

Looking for the problem I found that if the mosfet is removed or its Threshold voltage is not reached, Simulink doesn't report an error

Changing the initial value for the capacitor voltage to a non-zero value may help the solver. Without the model is not easy to provide alternative solutions.
