If you could tell me what’s going wrong with this blender file here it is https://drive.google.com/file/d/1JnoMLXbxEInrXzp6hvdW_K0wb0Qsqn56/view?usp=sharing

I’ve made a viscous fluid

and I’m trying to get it to fill this cup but it keeps traveling through the bottom can you tell me exactly what I need to do to make this work thank you

That looks like a bad collider. Make something better. Give thickness to the walls and bottom of the cup.
