Re: [Paraview] PV 3.10.1 computing vorticity from vector field
Tim Gallagher wrote: This is outside of what I usually do, so I may not be much help. But once you have the vorticity at all verticies, that should include the verticies on the cylinder surface. Correct How do you extract the surface? Is it a body fitted grid or an embedded boundary/levelset to mark it? The geometry is a body fitted 3D cylinder unstructured mesh. I have an id array for each vertex. The id at interior points is zero. Each boundary vertex has a non-zero value. I set the id on the cylinder surface vertices = -3 The extract the boundary like this. 1-extract surface 2-connectivity 3-threshold with id for the cylinder. I would assume if you extract the surface in the pipeline downstream of the derivatives and interpolation filters, all of the variables would be available on the surface. I see the cylinder surface and display shows the variables available (vorticity is there). I can see the surface vorticity contours and clearly see where flow separation occurs. I would like to see surface streaklines of the vorticity. When I click on surface flow PV crashes. Maybe I need to transform the vorticity vector to r,theta,z coordinates before doing surface flow. What do you think? Stephen Unless of course the surface is looking for cell data and not point data, in which case you would skip the second interpolation filter.

Create a vector, U and obtain the curl of it by using: curl(U). I think your version of Python must have numpy available, though. I tried both the suggestion of Time and Andy, both worked well. Now that I have the vorticity at all the vertices. What must I do to obtain the surface flow (vorticity) and surface vectors? The solution is for the Navier-Stokes equations for flow over a cylinder. I know how to extract the surface of the cylinder but how do I tell PV to use the vorticity and not the velocity field?

I'm about to change this filter so that it will work with all types of VTK grids.

To do those things, you want to make it Point Data with another CellDataToPointData filter. The calculator would see it if you changed it from point data to cell data. But since you want to do other stuff with it, add the interpolation filter again and then it will appear with the rest of your point data.

[Paraview] Using vtkFileSeriesReader with vtkSpyPlotReader
Hi, I'm trying to read in a restarted CTH Data set using vtkSpyPlotReader with vtkFileSeriesReader. But I cannot figure out how to transfer the information from the meta file (*.spcth-timeseries) to the spyplot reader. a section of my code: vtkFileSeriesReader* restartReader=vtkFileSeriesReader::New(); vtkSpyPlotReader* cthReader=vtkSpyPlotReader::New(); vtkDummyController* controller=vtkDummyController::New(); cthReader-SetGlobalController(controller); restartReader-UseMetaFileOn(); restartReader-SetMetaFileName(filename.c_str()); restartReader-SetReader(cthReader); But the spyplot reader doesn't have the information it needs; so it will not let me update the pipeline. Any suggestions? Thank you in advance.

Re: [Paraview] Using vtkFileSeriesReader with vtkSpyPlotReader
Hi, The SpyPlotReader already handle file series. The file extension just need to be a numeric value ie, spcth-a.0,spcth-a.1,spcth-a.2 while the name of the file start with spct.
