I have a problem with physics. I am trying to make a spoon removing a fluid in a cauldron. The problem is when I introduce the spoon into the liquid the liquid splashes a lot.

enter image description here

I tried changing a lot of parameters, even viscosity from Water to Honey but it changed not enough. Resolution is 150 for Domain.

Maybe is because of keyframes? The spoon moves too fast?

I attach the blend file if it helps you.

Thank you.

  • $\begingroup$ I know this has already been answered, but how do you get the fluid to simulate? I've tested your file and can't get the fluid in the cauldron to actually move/churn. Asking because I actually want that splashy effect you're getting for another project. $\endgroup$

I found the solution:

When the spoon is selected as Fluid/Control there are two parameters which must be changed:

Attraction strength: with positive value attracts the fluid and with negative repels it.

Velocity strenght: the influence of the spoon's velocity with the fluid.

Just try configurations until get what you like.

In the "Liquid" menu in the domain settings, try lowering the FLIP Ratio value.

The fluid simulator actually uses two methods to generate fluid data, FLIP, and PIC. FLIP results in a splashy, unstable liquid while PIC will give a more smooth and less splash-prone liquid.
