Re: [Paraview] Fwd: Gradient of Unstructed dataset
Hi Berk, After I loaded CGNSReader , I achieved success in getting the gradient of a certain scalar same with Ensight and SC/Tetra post . I used the Paraview Nightly build g544b3a7 for mac. Thank you !! But I could not found the CGNSReader in nightly builids for win 32bit and win 64bit. 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.

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.

Re: [Paraview] Fwd: Gradient of Unstructed dataset
Hi Berk, Gradient of Unstructured dataset filter seems working nicely in your computer... I am using Paraview in MacOS Yosemite and Windows 7. In both setting, the computed gradinet values are half of Ensight and SC/Tetra post. Is your Paraview running in Linux ? Client information is also attached to show you my computer enviroment. Grad-P.vtm is attached with this mail. Gradient of Pressure was calculated with Gradient of Unstructured dataset filter, and saved as VTK multi block files. Select GradientOfUnstructuredDataSet1 in the pipeline browser, File - Save Data... - Files of type VTK Multi Block Files (*.vtm). I don't know how to save out the output of the gradient filter as a .vtk file (or .vtu). If vtm is not suitable, please teach me how to output a vtk or vtu file. Thank you for your hard work and efforts very much.
