FLIP - Pump from Object - Volume

Recommended Posts

Hi

I am trying to add extra velocity to a flip fluid from an object. I have tried setting this up manually by converting an object to a volume, giving it a velocity and then using a source volume attached to the flipsolver. This is the same setup as the Pump from Object Shelf tool, which I am now using!

When you give the Fluid Source Volume a uniform Velocity or a curl noise these new velocities are then added to the flipsolver over the whole bounding box area of the pump object and not the actual volume of the pump object. I have attached a simple file using a torus so that you can see the issue! I like the setup but does anyone know how to get the pump object to behave properly?

What I really want to do is a a slight curl noise around the hull of a boat!

Thanks for any help!

You can add a vopsop between the torus and Fluid Source node, put a curl noise and direction vector in there (if you want directional velocity), add them together and pipe it into the point velocity output. Then you won't need to bother with the Add velocity or curl noise in the Fluid Source node.

I'm sure there are other many other ways using volumevops etc. too...

OK, I switched of the velocity from the Fluid Source added a vopsop with a curl noise and ........ great! it works! very simple! Thanks paul

HI,Gramx.

I want to do the same effect in flip.

I add the noise in vopsop,but it does not work!

Can you show me more detail about how to add the noise and velocity in flip!

I really a newer in houdini!

Thank you very much!!!

I have attached scene file with vopsop so you can see how it works. If you want more details then you increase points on surface before the vopsop. Hope it helps!pump_from_object2.hipnc
