I’m getting some strange behaviour when using the fluid simulation, I’ve probably not enabled the right feature but after many hours of trying I can’t find what I’m doing wrong so any help that can be given would be greatly appreciated. I’ve created this test file to illustrate the problem I’m getting rather than the original file that runs a simulation for much longer to make things easier.
The problem I have is that fluid that is meant to be sticking to a moving obstacle is dissolving or behaving in unusual ways when the direction of movement of the obstacle is changed.
In the file below I’ve got a cylinder on a stick set to No Slip being dunked into some viscous fluid. When it is pulled out of the fluid the fluid is sticking to the top of the cylinder, however when the cylinder starts to go down again to be dunked again the fluid on top of the cylinder dissolves, then reappears then disappears again before it is dunked again. It isn’t simply just a case that the fluid is running off the obstacle as it happens even if the top of the cylinder is concave like a spoon.
As I’m a new user I don’t think I can post a link but I have uploaded a YouTube video to show the problem with the frames that the issue appears in slow motion for which I have included the link in the text editor panel in the blender file attached so the issue can be viewed without having to wait through a lengthy bake. In the file the simulation is set to a resolution of 200 however when I’ve tried simulations at resolutions of 500 the problem still persists so I don’t think it is an issue of resolution.
Thanks in advance for any help that can be given.
