Re: [Paraview] how not to scale the thickness of the Arrow Glyph?

Re: [Paraview] Fetching data from xdmf temporal collection
Hi Jean-Michel, just to mention, I don't think VTK is significantly more efficient than ParaView. In practice you shouldn't feel a difference, since all the heavy data handling is anyways done by VTK. Anyway, I attached a script that shows you how to read XDMF data, step through the time steps, wrap the data for numpy and print out some basic infos. Regarding the GetOutput() method, to get data object from the XDMF reader you have to use the GetOutputDataObject(0) method. But I don't know the difference between the two of them, and this also may depends on your VTK version, I'm using 6.2. -Armin On 03/23/2015 03:15 PM, Jean-Michel wrote: Armin, you said you would rather use vtk directly to access raw data in xdmf files.

Re: [Paraview] how not to scale the thickness of the Arrow Glyph?
Dear all, Well... I'm still attached to the original idea, and after some googling I found the following article and mantis entry... https://paraview.uservoice.com/forums/11350-general/suggestions/450560-glyphs-scale-only-the-arrow-length-instead-of-the http://www.vtk.org/Bug/view.php?id=13660 So I've loaded the ArrowGlyph plugin onto my ParaView 4.3.1 32-bit (on linux (compiled by myself), and on windows vista (a binary downloaded from the paraview site)) and applied it to my data. But even though I can see glyphs and can change e.g. radius of shafts, I can NOT choose any Scaling Array; the pull-down menus do NOT respond to clicking... Any clue to this?

Date: Wed, 25 Mar 2015 23:01:51 -0400 Hi Kazuyoshi, I do not think the glyph filter will do what you want it to. You might use a Python programmable filter[1] to turn each point into a line segment (i.e., a line from (x,y,z) to (x+dx, y+dy, z+dz)). Then run Cell Centers on the resulting line segment data and add oriented, unscaled cone glyphs at each cell center to indicate the direction along the line segments. That would draw lines along the path plus cones pointing along the direction of the path.

Re: [Paraview] PlotSelectionOverTime filter in python
Hi Paul, This should get tracked in the Python Trace functionality. I'll add a bug report for this. For now you can do it manually with something like: w = Wavelet() selection = SelectCells(query=id==0) ec = ExtractSelection(Selection=selection) ec.UpdatePipeline() This should select the first cell of the Wavelet source and extract it. For point selection replace SelectCells with SelectPoints. There's probably more complex selections for multiblock data sets but talking to you I thought you had an unstructured data set. For the query string, you can see how more complex queries are created in the Find Data option under the Edit menu. Let me know if this doesn't work for you.

Re: [Paraview] PlotSelectionOverTime filter in python
Hi Paul, I think because of the bug you'll need to cobble together the Python script you want. First you can try doing everything in the GUI and recording it in a single trace and see if manually adding in the: selection = SelectCells(query=id==0) ec = ExtractSelection(Selection=selection) ec.UpdatePipeline() PlotSelectionOverTime(Input=ss,Selection=ec) parts as needed. If this doesn't work you may have to record everything up to the above point. Then do the selection and PlotSelectionOverTime() manually in the GUI as well as appending to the Python script, and then finally doing another trace with the final couple of steps. Let me know if that works for you. Regards, Andy On Thu, Mar 26, 2015 at 4:10 PM, Paul DesJardin p...@buffalo.edu wrote: Hi Andy, Thanks for the quick response.

Win 32bit, g04df19f, and Win 64bit, g04df19f In the windows version, I found GMVReader, but it didn't work with CGNS ( I tried). By the way, my final goal is to calculate the wall shear stress of vessel from velocity and wall normals. Now, the barrier has been removed by you, and I can calculate and visualize the WSS in Paraview. I already see it in SC/Tetra post and Ensight. But Paraview makes more beautiful graphics and I am very happy. Thank you for your kindness !!!

There you should see the CGNS plugin. Load it. After that, when you open the CGNS file, it will give you an option to use the plugin based reader.

It makes sense to me, but I have to wait for the future version since I dont have skills to integrate the CGNS reader plug-in into the Paraview binary... Thanks anyway and Best wishes, Masaaki 2015-03-25 2:13 GMT+09:00 Berk Geveci berk.gev...@kitware.com: Hi Masaaki and others that may be interested, I identified the issue. The default CGSN reader that we use (which is from VisIt originally) produces incorrect results. The pressure values are incorrect. If you load the CGNS reader plugin and open the CGNS file with that, you will see the correct results. I tested this with the nightly binary of ParaView. I will ask someone in the ParaView team to disable the VisIt CGNS reader and move the plugin into ParaView proper so that we can use it by default.

The high temperature for today and tomorrow is 30F (-1C).

Nightly Builds of Paraview was downloaded on 2015-Mar-18 (ParaView-Windows-64bit-NIGHTLY.zip). Gradient of Pressure was calculated using Gradient of Unstrucutred Dataset filter and Z component of Grad (pressure) was visualized. Unfortunately, Nightly build did not settle the problem... The computed values by nightly builds were also half compared to those of Ensight. Could you take a look of the result in the attached PDF? Thanks for your continuous help.

When using the CGNS plugin from ParaView development version, you get the same picture as Ensight. My
