How do i solve the following simulation error??

When i run a physical model of half wave rectifier in simulink it shows the error for the solver block...
'Calculation for differential and algebraic state derivatives failed.'
How do i solve this??

Hi Paranshu,
It is hard to say based on the information that is provided but it may be due to several reasons. Internally, the Simscape blocks have differential equations that represent each of them. If the equations were not strongly written in the case of a custom block then this error can appear sometimes. Additionally, the solver may be limited to being unable to solve these type of equations. Try reducing changing the solver to either ODE15s or ODE23t and reducing the Absolute/Relative tolerances in the configuration parameters to 1e-6.
Does this model use any custom Simscape components and does it error out immediately or somewhere midway through the simulation?

Would you be able to attach the model so that someone can have a better look at the error?

Hi Paranshu, How did you solve this. I am observing the same problem with my simulations. No custom block have been used.
