Not Enough Nodes Found netlist error

Question

I am working on a project for a voltage multiplier/divider and am working off this schematic from texas instruments (I have attached a pdf of it). When I try to simulate the circuit, I get an netlist error on every LM101AD Opamp saying Not Enough Nodes Found and the circuit doesnt work as it is support to. I have attached the circuit in multisim and the original drawing. Thanks for your help, -Alex

Answer 1

The reason for the error message is that there are more nodes on the opamp's model than are mapped to those nodes. This component has multiple models, and this is a problem in the database only with the default Linear Technology/LM101A model.
You can select the model in the Place a Component dialog when you place or replace a component (look for Model manuf./ID).
I've made these.changes to your file. It will now simulate without errors, but the rated capacitor blows up. I haven't looked in detail if this is what to expect (electronics is not my forte).
I've also added this to our defect tracker so we can resolve this in a future release and improve the error message.
