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.
