Can anyone help me solve this convergence issue for my op-amp circuit?

At a quick glance, it appears you have your power supplies reversed. VEE should be minus supply, VCC should be positive.

Can you quickly help me with this one also?

I am not sure about what the issue could be but this post could be useful to resolve simulation erros:

If you go into the symbol properties, and turn on symbol pin names (see image). Then in schematic view the error becomes plainly obvious. The+ 20 and -20 are backwards (based on the voltages listed). I have not tested this, but I am sure that is the problem.

So do I need to repost in the other forum, or what? Or can the mods fix that? I would rather my time to answer the question not go to waste.

Thanks

Is not necessary I did the comment to let him know that he should not duplicate forums! Leave your answer Here!
