Popping in Fluid


Hey everyone, I just started learning Houdini about a week ago and am really enjoying it. *However, I have a question about Fluids: *I was playing with the new Suction fluid but found in the render there’s a strange ‘popping’ or bubbling where voids are getting filled up, like there’s a few frames where Houdini isn’t sure whether it should be filled or empty as they close up. *Anyone know what might be causing this?

My best guess at the moment is there must be a setting in the Particle Fluid Surface node that needs to be reduced. *Maybe the voxel scale? *or the Droplet Scale? *The brain .obj isn’t very large in the scene, so I’m guessing I need to shrink the volumes that are being converted to compensate.
