Simulink help?

Hey guys. Im trying to simulate some circuits in MATLAB's Simulink, and I always get some weird graph which is not sinusoidal at all. I wanted to know if anyone could tell me which block am I missing if I want to get a good sinusoidal wave.

Here are the pictures of the circuit and the graph I get:
