Simulating an OpAmp

    1. The problem statement, all variables and given/known data

    I need to simulate an OpAmp in Simulink but I can't seem to find an OpAmp block that works in SimPowerSystems, so I kept searching and found out sort of an equivalent. However, the simulation still gives me an error. I would highly appreciate if anyone could tell me what I could do to fix it.

    3. The attempt at a solution

    Here is what I have so far:

    The OpAmp equivalent is the part where I put the two voltage measurements followed by the adder block, and then the gain and saturation blocks.
