Hi ZiwenZhang, I’ve looked into it and I can so far confirm that there is some error when executing the freeSurface examples on GPU. Running them on CPU gave me correct results.

You mentioned that the fallingDrop examples run correctly on your end. Can you tell me how the visualization of fallingDrop2d looked for you?

For me, the fallingDrop examples show movement of the liquid, but the behaviour is faulty: The liquid pool on the bottom ‘curls up’, when it is supposed to ‘splash’ to the sides.

Other examples such as rayleighInstability or breakingDam show no movement at all.
