Hello Dr. Sassi. I wrote most of the times my name all in small letters. But both are fine
At first I did not get what you talked about....about no animation. Don't know what exactly happened because there was liquid animation, and the file I sent you had no more?!?!
What di you change when you say "Your file didn't have any fluid animation, so I reduced it." The Nyquist Frequency, is understood
I found the Normal issue a bit later, did change but without success. So you rather go for Volume collision and use some preprocessing, instead of Surface and Thicken on the geometry.
I'll continue working on it and let you know how I'm doing
