Fluid Sim, Fluid Sim, fluid sim…Can anyone tell me how to use fluid sim to fill a bottle? I know a litte about fluid sim…And can someone explain a little bit more about fluid sim? like is the domain object the one that gets turned into liquid?
Yes. The domain object is used as a container for the fluid simulation meshes. To fill a bottle, the process is fairly straight-forward:
- establish your domain (use a cube).
- establish your fluid (anything will work, but I prefer a small cube or icosphere) and place it within the bounds of your domain.
- establish your obstacle and place that in the domain.
Now, in order to get things to look right, this is where you have to play a bit. If the fluid is interacting with your obstacle weirdly, try changing from ‘Init Volume’ to ‘Init Shell’. If the fluid is not interacting with the bottle at all, your bottle may be a bit thin. In this case, you can either increase the resolution of the simulation or you can place a dummy object with greater thickness as your obstacle (then after running the simulation, hide the dummy and render with the bottle).
Ok, thats 1 problem down, now next problem is that when I bake it doesnt bake right…the domain will bake but it will dissappear, so thus I have no fluid sim…any ideas on how to fix this? the only idea i have is to make a new .blend file.
Are you viewing the simulation preview or the final? Check the final and see if you see anything there. Also, if you want to select the domain, you can always use the outliner, or move beyond the last frame of the simulation and you’ll have your cube again.
What sort of fluid are you using? Just a fluid or an inflow? Do you have any forces on your fluid? It doesn’t take much force to move the fluid (I’ve vary rarely ever had to go above 0.5 in any direction). These are just a few things to look into, but they should help.
I had preview, but even when its done baking, i play the animation and nothing, the cube is gone. And im using inflow, -1 on the Z axis
Ok I figured out how to fill a bottle now, how do i make it have More fluid?
What do you mean by more fluid? Do you want the simulation to run longer, or do you want to more fluid initially? You’re using inflow with a fairly high z force. You could increase the force (I don’t recommend that) or you could increase the size of your inflow object (a bigger pipe in, if you will).
