Create velocity volume from single volume

[bobbybob]

How is it possible to convert a single volume, to 3 volumes (velocity)

I have shaped form that I am converting to a volume. I then need to convert that volume to vel.x vel.y and vel.z, to create a velocity field of. it is not optimal to just create a bound and then convert it via a "Volume" node, because I need to keep the original shape.

To explicitly answer your question:

Take your current volume, and place 3 "name" nodes, in each one link it to your current volume and name in the string parm "vel.x", "vel.y", "vel.z" -- place a merge, and combine your original volume, along with the 3 volumes that have been renamed. You'll now have your original volume, and 3 fields for vel.

I think with more context though, there will be a better answer.

Thanks. What I wanted was to create a velocity field only in the object.

I ended up using 3 volumes for the velocity and one more as a density volume that I am using as amplitude for the noise, to keep the noise in the shape itself.

Maybe it would be a bit faster to copy the volume and rename it as you mentioned @TheDude, Thanks for your answar.
