Thanks for your answer.
The error I get is the following message
"Simulation error"
"A simulation error has occured. Would like to run the Convergence Assistant to attempt to resolve this problem automatically?"
When I answer YES is popping up a windows with "Attempting to resolve convergence issue"
Then a bar green appear and it seems is trying to resolve the error with several steps, but after completed is always written Simulation error still occurs, and that's doesn't help me to understand what is wrong....
Final message is "Failed to resolve convergence issue"
I think it should be better to have a indication of what is wrong instead to try to resolve the "convergence issue".....
I get the same error also if I connect a LED with a battery of 12V and a switch in series, with a resistor to big or to small....for example 10K or 1 Ohm. With a 1K resistor, it works ......
Very arcane behavior...
