MATLAB: SINEWAVE IN SCOPE (simscape)

Question

Hello, I connected an ac voltage source to a voltage sensor and then trough a ps-to-simulink converter to a scope, in order to see the voltage graph. I use an ode23t solver and the only thing I get is a straight line on the x axis (with value ewual to 0). No sinewave looking voltage/ I set simulation time to 0.1. Why is this happening? Do I need to use different blocks? SCOPE is not appropriate for simscape and physical signals?

Thanks

To see the sinusoidal voltage variation you need to reduce the step size of the simulation. Go to Simulation -> Configuration Parameters and change the Max step size parameter to be smaller than 1/(2*frequency). For example if the AC frequency is 60 Hz, set the parameter to be 1/120 or 1/240.
