[Paraview] limiting streamlines in paraview
Hello, Is it possible to compute limiting streamlines in paraview (for exemple on a vessel hull) ? Thanks to anyone who have the answer. -- _ Luc Bordier R&D Engineer luc.bord...@sirehna.com http://www.sirehna.com SIREHNA 1, rue de la Noe BP 42105 44321 NANTES CEDEX 3 FRANCE Tel: +33 2 51 86 02 80 Fax: +33 2 40 74 17 36 _ ___ 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

I am not sure I understand. You are interested in surface constrained streamlines? I am guessing from an inviscid simulation? -berk On Wed, Jun 3, 2009 at 4:50 AM, Luc Bordier wrote: > Hello, > > Is it possible to compute limiting streamlines in paraview (for exemple on a > vessel hull) ? > > Thanks to anyone who have the answer. > > -- > _ > Luc Bordier > R&D Engineer > luc.bord...@sirehna.com > http://www.sirehna.com > SIREHNA > 1, rue de la Noe > BP 42105 > 44321 NANTES CEDEX 3 > FRANCE > Tel: +33 2 51 86 02 80 > Fax: +33 2 40 74 17 36 > _ > > ___ > 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 > ___ 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
Re: [Paraview] limiting streamlines in paraview
At least I am interested in this. In general streamlines are better in 3.7dev, stream tracer has obviously improved. However generating constrained streamlines with emitters on one part of a multi-block dataset streamlines often terminate at the border to another part - reason for termination ist "6" - any suggestions?

Re: [Paraview] limiting streamlines in paraview
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 this link 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. _ Luc Bordier R&D Engineer luc.bord...@sirehna.com http://www.sirehna.com SIREHNA 1, rue de la Noe BP 42105 44321 NANTES CEDEX 3 FRANCE Tel: +33 2 51 86 02 80 Fax: +33 2 40 74 17 36 _ Berk Geveci a écrit : I am not sure I understand.

Re: [Paraview] limiting streamlines in paraview
Well I think of two ways: 1. export wall shear stress components from CFD-code and use these (what we currently do), this seems quite ok. 2. Calculate wall shear stress in paraview. I currently have no filter to do this but would be interested in one...
