Hi all!

 Im ready to go now (although electricity is no stable yet)
 Im now doing a little research on physically renderings and vortex
methods for fluid simulations in order to collaborate with Matt Ebb and
Daniel Genrich.

 And I have a question:

 In order to obtain velocity from vorticity fields many researchers use a
lagrangian approach, Vortex in Cell and vortex particles or vortons, but
I need a way to resolve in a finite difference way.

 In  a lot of places appears the relation between vorticity-stream
function-velocity but this is only 2D, I need a way to obtain 3D velocity
from 3D vortex field.

  I have implemented a method that return the velocity form the curl field
but not the irrotational component of it. Suggestions, pappers? a lot of
pappers on vortex methods are comercial, they guard very jellously those
methods, but sadly for them If I find a way I will release it publically

  ...continue my struggle.

                                      Regards Farsthary
