chained op-amp simulation error

[Hexile]

Hello. The simulation always halts here. is there something wrong?

(no, the assistant, while pretty good can not solve this issue)

It does work fine with the "virtual opamp" parts.

Hello,

Did you tried to source the op-amps not from the VDD and VEE but with DC power source (basically the battery)?

[Hexile]

I did not try that yet, but to me it should make no difference in my mind. I'll give it a try.

[VA.KI]

VDD and VEE have different properties than power supply.

Also, what warnings or error Multisim shows up at the bottom (in the spreadsheet vew)?

And having ground in the schematic affects as well.
