indicate the particle that was at

at time t=0. We will want to find all
unknowns in terms of these tags.
In a Lagrangian description, we label the fluid particles with tags.
For example, let indicate the particle that was at
, , at time t=0. We will want to find all
unknowns in terms of these tags.
For example, we want to find 
. Then
Example:
2D ideal stagnation point flow
Shape of the particle paths:
is constant.
