Limiting streamlines and Vortex Lines are features that are available in
FieldView and that i would like to reproduce in Paraview.
from what i understood, limiting streamlines are curves on a surface for
which directions are thoses of the vanishing fluid velocity
something like : dx/tx = dz/tz (with tx, tz : viscous shear stress)
(found in
http://books.google.fr/books?id=rfszzPiuDfAC&pg=PA368&lpg=PA368&dq=%22limiting+streamlines%22+formula&source=bl&ots=CHvs_wxF16&sig=CUlIajS0GkjKPEkodrDy-bb6nBM&hl=fr&ei=hTkmSpuGO8vGsgbKooTYBQ&sa=X&oi=book_result&ct=result&resnum=1#PPA369,M1
on p368-369)
so i guess i need to have the viscous shear stress (something like
du/dy, and dw/dy)
surely i 'will have to use these as a vector for streamlines filter
but surely there will be some projections to be made regarding to the
surface normals...
I will try to dig a little in order to have a custom filter about this
but any comments or help are welcome.
