[Paraview] Save selection as part of VTU file
Hi. I am doing a custom made FEM solver in one of my studies. I have a 3D geometry that I save as a VTU file and do my computation on. To impose boundary conditions I would like to be able to select the edge faces of cells on the boundary of a geometry in ParaView. Then I would like to save the selection as a sort of list of edges inside the VTU file i export. I know how to select points, and cells, but how would i easiest select cell faces? When I have selected the cell faces, how do i export them so that my FEM program can read it? ___ 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://public.kitware.com/mailman/listinfo/paraview
Re: [Paraview] Two questions regarding animations in batch
Thank you, Utkarsh! It tried CameraAnimationCue, but it still segfaulted with the error No camera to animate. Therefore, I added Show(reader) Render() before creating a cue. Now it works. However, the resulting movie is just one black frame lasting for a fraction of a second. How can I tell the script to add the object itself to the movie and to do it for every frame? I have over 100 frames in .vtk files. -- Morten On Mon, Feb 4, 2013 at 6:02 PM, Utkarsh Ayachit utkarsh.ayac...@kitware.com wrote: Morten, (i) Use CameraAnimationCue instead of KeyFrameAnimationCue. (ii) Try using the WarpByVector() filter.
