Hello,
I have been trying to simulate a cylindrical model using structural mechanics(time dependent) with a transient displacement point source (0.00005*sin(2*3.14*3000*t)*e^(-((t-t0)^2)/(2*(sigma^2))) [gaussian pulse] in y direction. I have applied a low reflecting boundary condition at the ends of the cylinder. The time step for the simulation is 1e-6 and I have been using a 'finer' physics defined mesh.
radius=10mm
length=1500mm
I have multiple points(and not directly probes) added to the model which would act as sensors to measure the displacement in y direction.
With the data generated from the simulation when I plot the dispersion curve for the phase velocity vs the frequency, I get varying plots with the change in the location of the sensors.
Please let me know what am I missing while modelling, which is leading to such an erroneous results.
