Changing Frequency causing Error? Answered
I am wondering why the arrival times for my signals change when I change the frequency. Everything else is kept the same and I am only changing the excitation frequency. I am simulating through Titanium Grain Structure using water boundaries with absorbing boundary conditions.
I am using a Ricker wavelet and as you can see from my image as I increase frequency, the arrival times shorten. Not sure why this would happen. Also, my front wall signals should have the same amplitude as when leaving the excitation point, the wave is only travelling through water until it reaches the front wall.
Another problem is the amplitude of my back wall signals are increasing with frequency when I theory they should decrease. I have tried to account for damping in my Titanium microstructure and the water. Just wondering if anyone would have an Idea why I seem to be getting backwards results.
