Input vector operator

Hi,

I am trying to implement the following equation into my python code

$$(v.\nabla)v$$

in which v is a vector field. How would you do that? Any help would be appreciated.

Many thanks.

Have you looked at the navier stokes demo?

I think I must have missed something the last time I saw the demo. Thanks for suggestion anw.
