Re: Help using Linear's free simulator

Hello ,
I am trying to simulate a simple opamp circuit with Linear's LT Spice
simulator. The circuit is simply a single supply opamp, the minus
input connected to 0.5V and the plus input connect to a 1V sine wave.
The output is connected to ground by 1K R.

According to my understanding, I should have at the output a square
wave. However, I am getting only a dc value. Can someone check
my ''design''

I have the LT Spice asc file:

You have power hooked up backwards to the opamp.
