I end up using a POP drag.I am not sure if it's correct. But the water becomes much more calm than before.

I am trying to do water goes into a room from an opening door. I put a cube as an emitter in the hallway, and another two cubes as drains in the end of hallway. The requirement is no waves, so the water needs to go up just like a swimming pool. I tried different settings,but there are always waves as long as the water collides with the wall. Is there a way to avoid waves? Thank you!

Hi, I'm trying to do particle fluids inside a moving balloon. I build a geometry and change it into fluids.However,the fluids become less after a few seconds while the ballon is moving.
Here is the result:

What should I do? I hope someone could help me. Thank you so much in advance.
