Hi, I got a problem with the Frequency-Domain Modal Analysis. It works fine for the attached model until I add an electrical circuite connected to my device. I get the error "Feature: Modal Solver 1 (sol1/mo1) - No eigenpair solution detected." and have no clue how to solve that.

Any suggestions?

Best regards, Matthias

Meanwhile I found out that by changing some properties of the Modal Solver, the error disappears, which leads me to another question: Is it possible to combine the Frequency-Domain Modal Analysis with an Electric Circuite Interface so that I can see Voltage and Current through a Resistor for a given harmonic perturbation of a vibrating beam, like in the model file above?

Br, Matthias
