I think this is the right section to post this in, anyway I am having some trouble with the fluid simulator, I am trying to make fluid fall into a funnel and go through a tube to fill up another container, however whenever the program either completely ignore the funnel or the funnel and tube mesh itself becomes a fluid >.< Any help please?
EDIT: file attached: The thing I am trying to get it to do is have the fluid fall into the funnel, go through the tube, and fill up the “G”
Methinks you are confusing the domain with an obstacle. Short tutorial here, but I suggest you look up a tutorial somewhere else. Use a cuboid domain, a cuboid fluid, and a simple obstacle. Anyway:
The two main fluid creator types are “fluid” and “inflow.” Fluid makes the volume of that object will determine the volume of the fluid. Only that volume. None else. Inflow makes the object a fluid “source.” Fluid will flow from the object’s volume for as long as you set it to.
The domain of the fluid is not exactly the place where the fluid is held. The domain is the volume in which the simulation takes place. The fluid will not be able to flow out of the domain shape. You should have the domain include all components of the simulation: fluids/inflows, obstacles, etc. It is the world in which the fluid simulates. The funnel and the container do not make up the world. They are things in the world that interact with the fluid in a way that directs the fluid’s flow.
I’ve pretty much already described obstacles. They are things that the fluid collide with, but not the outermost extents of where the simulation can happen.
You should note that the domain will actually turn into the fluid in the simulation. Not to worry. The fluid or inflow still determines the volume of the fluid or fluid source, and the fluid will stay within the bounds of where the domain was.
Sadly I already tried that >.<, when I set a cube as the domain and try it, the fluid tends to pass through the funnel even though I set it as an obstacle =s, although I do have a theory as the problem, does an obstacle like a funnel need any specific characteristics?, what I mean is the funnel is basically like a piece of paper rolled into a funnel, instead of a solid object, instead of being a solid funnels it’s purely 1 layer of faces, i’m not sure if fluid has any problem with interacting with flat objects?
Just attach your blend file to your post (press the Go Advanced button and use the paperclip icon) or some other host site so others can actually see what you want to do rather than go round the houses trying to imagine what you have or haven’t done. It’ll help immensely those trying to help you.
Some initial observations:
The cube you want to use as your domain object hasn’t been set as a domain in the fluid settings.
Reduce the size of the domain cube so it is as small as you can get away with to surround all your objects, you are wasting fluid resolution if its bigger than needed.
For all your objects use Ctrl+A to reset their scale values back to 1 to ensure correct simulation
For your obstacle change it from a Volume to a Shell.
Your fluid object needs an initial velocity if it is an inflow. Set a negative Z inflow velocity in its fluid settings.
To enable the fluid to flow through a small pipe you will need to really increase the fluid resolution.
well it was set as my domain before, than I unset it so people looking at it could get a fresh idea, but thanks for all the tips =D i’ll try them out in a bit
