[Nek5000-users] Point votices at inlet

[nek5000-users at lists.mcs.anl.gov]

Hi neks,
I still cannot for the life of me figure out how to apply this vortex
method at the inlet to generate turbulence. Let's say i specify a point at
the inlet plane say for example at the coordinate (x1, y1). I need to apply
the Biot-Savart law at this point which has a term like (*x_i  -  x) **(Note
these are vectors) where x_i is the point i specify and x is all the nodes
on that plane. How do i call on the nodes to do this vector subtraction?
Can anybody help?*
