Hello all,
I am trying to run frequency domain modal analysis of a cantilevered beam. I have built the model in Comsol 4.1 and have assigned desired material properties. Have applied fixed constraint criteria for one end of the beam. Now, the resonance frequency of the beam is 610 Hz. I am interested in the analyzing the beam between 400-900 Hz. The problem is that when I run the model I do not get any modal displacements. For all the frequencies I get '0' displacement throughout the model. But this can not be true because the beam has resonance at 610 Hz. I have tried using boundary load at the fixed boundary and body load also. But the problem persists. I am attaching the model with this mail. Can anyone suggest where am I going wrong?
Thanks
Sankha
