school project problem (a very simple circuit, 100kb)

[freakcrazy]

hi all! i am an university student and it's my first time using multisim. i made a circuit which consists of 2 non linear dependent components, 1 integrator, 1 voltage source, 2 voltage-controlled components, and an LRC parallel circuit. this is to simulate a MEMs device with electro-mechanical domains. i can not simulate the circuit and i am afraid that my circuit is plain incorrect. may someone please take a very quick look at my circuit and inform me why the circuit doesn't work?

Hi there,

This is a very interesting closed loop circuit that you have. I think the problem is originating from your NONLINEAR_DEPENDENT source A1. The denominator may go to 0 in which case Multisim cannot find a solution to the circuit and can't simulate.

Try setting some initial conditions on some nets and capacitors (and inductors, but your circuit doesn't have any) and try again. Multisim might be able to simulate your circuit if your initial conditions didn't cause the denominator of A1 to be 0.

Good luck!

Thank you so much YYAO!!! your reply gives me great insights. :manhappy:
