The simulation tells me node1 is -7V and node2 is 28V. Nodal analysis says node1 should be -13V and node2 should be 39V. I've checked and rechecked the values and polarity of each component. Could someone clarify. Is my math wrong, my simulation not setup properly, or is this a problem with circuitlab?

Thanks for the reply. Your simulations are correct and match with the nodal analysis.

Hi @jelloyd, is it your intention that for VCVS1, the (+) control terminal and the (+) output terminal are connected together (both to NODE1)? I will need to take a closer look, but I am suspicious that that may be the source of the issue in the CircuitLab simulation.

OK -- this issue has now been fixed and CircuitLab gives the correct result (V(node1)=-14V, V(node2)=42V). Thanks for the report!

Awesome. Sorry for the late reply. Thanks for fixing the issue.
