Hi,
I am trying to simulate a 3-D beam in COMSOL v4.3. This beam is free in one end, and in the other end, I want to applied a sinusoidal boundary displacement input D(t)= Damp*sin(2*pi*f*t).
In the Frequency Domain study, I can add varying frequencies, but how to apply that boundary excitation? I am not using structural mechanics modulus but using PDE weak forms instead.
Thank you very much
Dan
