Hello, This is an addition to my previous mail about Surface Streamlines:
After several tests, I can obtain some pieces of surface Streamlines on non planar surfaces (with the Wiki example for Custom Filter as with my own data). I have to use a very low value of "Initial Step Length" of the Custom StreamTracer, but I get always more or less short pieces of streamlines. never a full streamline from the seed point to the border of the surface. So I have to put many seed points all over the surface to cover the surface with pieces of streamlines in order to have an idea of the surface flow.
What I would like to get is a full streamline extending over the whole surface from a given seed point. As an example, let us consider the fuselage of an aircraft. I would like to put some seed points on a circle around the fuselage at a given location on the aircraft axis. The seed points may be obtained using Mask Point on a Slice of the fuselage by a plane at the desired location on the axis. Then a Surface Vectors filter is applied to the fuselage dataset and the Custom StreamTracer is applied to the Surface Vectors. But all I can obtain is always more or less short (depending of the "Initial Step Length" value) pieces of surface streamlines extending around the seed points.
Is there a way to have full surface streamlines with the existing filters other than including LC or some other software?
Thank you in advance for your help. -- Richard GRENON ONERA Departement d'Aerodynamique Appliquee - DAAP/ACI 8 rue des Vertugadins 92190 MEUDON - FRANCE phone : +33 1 46 73 42 17 fax : +33 1 46 73 41 46 mailto:[email protected] http://www.onera.fr _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
