Limiting simulations-Dynamic Pull-in Cantilever

Hi everyone,

I have a quick question, Can I tell comsol to simulate till it reaches some theoretical value and the stop? I mean, what I'm trying to do is Simulate the dynamic behaviour of a cantilever beam under an applied voltage, so, when I solve the Static model, the coupled Physics(es and solid) work good cause I'm able to reach the Pull-In voltage as the value when the system fails to converge. Theoretically speaking, that's the point were the Electrostatic force equates the Elastic restoration force. Till here everything works logically, however, when I go to stationary study and simulate, there is no reaction, I mean there isn't even a convergence error or something, It just goes through the contact material, so I'm not able to get a Dynamic Pull in Voltage (which should be slightly different to the static). The point is that as comsol is not letting me obtain the dynamic pull in, I-m trying to do the following: Calculate the value of the force at which the system fails to converge in stationary study and then tell comsol in the time-dependent study to simulate just till it reaches that force value. I know it isn't the best approach but if it lts me extrapolate the dyamic pull in I'll live with it. Any help would be greatly appreciated.

Regards
