Hi. I have problem simulating this circuit in Multisim:
(LTSpice)
Here is scheme from Multisim:
When I run transient analysis, I got this:
------ Checking SPICE netlist for Design3 - Saturday, September 26, 2015, 10:58:03 AM ------
======= SPICE Netlist check completed, 0 error(s), 0 warning(s) =======
Transient time point calculation did not converge
Simulation canceled
Any idea what's wrong? Thanks in advance

I tried different models of opamp and I got same error. Here is my version of software:

And with previous version I didn't have problems simulating circuits with opamps. I think this problem has something with opamp power supplies, if I remove them, simulation starts without error. But opamp must have power supply to work 🙂

I get same error on Multisim 13.0.1 Power Pro. There is something wrong with this model of op amp in both versions of Multisim I tried.

Solved. I made stupid mistake, I didn't connect power supplies to opamp correctly.
