Hello everyone. I am simulating the behaviour of toothpaste on a vibrating membrane, wherein the speaker used is a Lenovo one of length 90mm and height 93mm (approx). I am not able to obtain a converged solution for the same. Can someone help me with the same?

I have already posted a question regarding the UDF, for which I have already got the solution. I have already tried many values for the under-relaxation factors for pressure and momentum, and reducing them to as low as 0.03 and in one case, I have even used a value of 0 for the momentum relaxation, but to no effect, as the result I am obtaining is physically irrelevant to the actual experimental results.

Can someone please help me out with the same, as this is really urgent.
