Hello,

I'm working on a 3D model in an attempt to simulate water waves in a tank generated by a sinusoidal pressure source. I've been able to create an otherwise equivalent 2D model which works, and have since then translated it into a 3D model, which doesn't always work. The 3D model works properly for low frequency and low amplitude pressure inputs, but beyond about 20 Hz, it fails. This suggested to me that I should increase the resolution of the mesh, though this did not appear to resolve my problem and significantly increases memory usage. I was able to avoid using too much memory by switching to a mapped mesh and using an iterative solver, though my model still didn't converge.

So I was hoping that someone here would be able to look at my model and make suggestions as to how I could improve it. I have uploaded two iterations of the model here: drive.google.com/file/d/0B2i7BRvuGZI5VnYyaFpSUVVCREU/edit?usp=sharing
cap3d_ale_40Hz_20Pa.diverge.mph is a model which I have most recently been working on, and still doesn't work.

cap3d_ale.mph is the model I initially made which works at low frequencies and pressures.
Finally, I have linked a working 2D model:

Any suggestions would be appreciated!
