I have been attempting to model a simple 5mm cube fixed on one side and with a sinusoidal time dependent stress on the opposite side. This should produce a propagating shear wave. I want to do this in order to animate the propagating shear wave.
The problem is that the applied sinusoidal stress does not change sign (change direction). The results should be similar to frequency domain solver results. Please reference my model. Note: study 1 is the time dependent study and study 2 is the frequency domain solver.
Any help to produce the above condition would be greatly appreciated
P.S.
My frequency is 4000Hz with a period of 2.5e-4s and my step size is 5e-5 so aliasing should not be the problem.
