The datasheet for the LM741 shows the power connections to be different from your circuit.
Here's the pinout for the LM741:
Pin 8 is "NC" which stands for "not connected." Pin 7 is the proper V+.
Asside from that, you can't run a 741 from 3.3V.
Its inputs and outputs must all stay a couple of volts away from the power rails. That's more than your ...
I don't think the '741 will work with a supply of 3.3V and GND. Almost of of its parameters are specified at V+=+15V and V-=-15V.
Change the supply voltages on your '741 model or use a different op amp.
