Limiting streamlines and Vortex Lines are features that are available
in FieldView and that i would like to reproduce in Paraview.<br>
<br>
from what i understood, limiting streamlines are curves on a surface
for which directions are thoses of the vanishing fluid velocity<br>
<br>
something like : dx/tx = dz/tz (with tx, tz : viscous shear stress)<br>
<br>
(found in <a
href="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">this
link</a> p368-369)<br>
<br>
so i guess i need to have the viscous shear stress (something like
du/dy, and dw/dy)<br>
surely i 'will have to use these as a vector for streamlines filter<br>
but surely there will be some projections to be made regarding to the
surface normals...<br>
<br>
I will try to dig a little in order to have a custom filter about this
but any comments or help are welcome.<br>

<pre wrap="">I am not sure I understand. You are interested in surface constrained
streamlines? I am guessing from an inviscid simulation?

<pre wrap="">Hello,
Is it possible to compute limiting streamlines in paraview (for exemple on a
vessel hull) ?
Thanks to anyone who have the answer.
