Re: [Paraview] Smooth seams in SILO files
Utkarsh: Thanks. That did the trick. I had to add a 'Threshold' filter in the mix to remove the ghost cells, which were confusing the 'Merge Blocks' filter. I've actually been staring at those boundary lines for over a year and a half and I've very glad to finally have them gone Again, thank you very much. -David Ortley On Wed, Feb 25, 2015 at 7:26 AM, Utkarsh Ayachit < utkarsh.ayac...@kitware.com> wrote: > Try applying "Merge Blocks" and before applying the > CellDatatoPointData.

Re: [Paraview] Smooth seams in SILO files
Try applying "Merge Blocks" and before applying the CellDatatoPointData. ParaView indeed treats each block separately. When you do "Merge Blocks", it will merge all the blocks into a single unstructured grid. This will make it possible to get a more reliable CellDataToPointData conversion across the block seams and hence avoid the seams on contouring.

[Paraview] Smooth seams in SILO files
Hello all, We have a CFD code that generates silo files using the silo library. For each dump in the simulation, there are multiple files per dump (one file per processor) and a single master file. When we use Visit to visualize a contour, the contours look good. When using Paraview (any version), there exist obvious seams at the file boundaries. To visualize in Paraview, we use the 'CellDatatoPointData' filter followed by the 'Contour' filter. I'm currently trying to track down if either Visit is magically healing over a bug in our implementation, or if the problem lies with Paraview somehow...or with how I'm trying to generate the contour (via the 'CellDatatoPointData' filter.) It almost looks like Paraview is treating the edge of each file as if it were an open boundary regardless of whether it is buttressed up against another file. Thanks for any help in this. -David Ortley ___ 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 Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
