A small suggession

Hmm I'm not entirely sure what you mean by making a simulation with a designed velocity...

Spacewarps are pretty simple internally, they take an input position and output a velocity vector. So they are functions and can take  arbitrary input. I guess I'm not seeing how you could create a flow that could be translated into a function like that...

Hey there! let say for e.g. if I have some particles revolving around an object, like a cross vector, or I have a surface force with texmap and gradient tracer............what if I want to use that for some other simulation like phoenixFD. then I can use that corss vector velocity or surface force velocity as spacewarp and apply in phoenixFD.....

I mean this is a very simple example......
