Carola the answer is "soon". ParaView's GUI already enables the setting of the so-called Cuttoff Array. In the GUI (I am assuming you use version 5.3), there should be a setting for the Density and the Mass arrays. And just below it, is the 3rd setting for the "smooting length" array. Unfortunately, we are waiting on a patch to the underlying VTK class vtkSPHInterpolator.cxx which currently has a small error preventing the correct setting.
By the way, I strongly suggest that you use a version of ParaView compiled with OpenMP, or TBB. You will see great speed-ups on a multi-core node, since the Point Interpolators (Line, Plane, Volume) are all parallelized on-the-node. Until the patch is merged into VTK, and ParaView picks up the change, you will be limited to setting the Density and Mass arrays. (Unless you compile your own ParaView, and I can tell you how to edit the source code to enable the smoothing array.) ----------------- Jean/CSCS ________________________________ From: ParaView [[email protected]] on behalf of Ellinger, Carola [[email protected]] Sent: Wednesday, March 15, 2017 6:47 PM To: [email protected] Subject: [Paraview] Help on SPHVolumeInterpolator Hello, I have astrophysical SPH (smoothed particle hydrodynamics) data that I want to interpolate for visualization in ParaView. I've found the SPHVolumeInterpolator filter to do that, but can this filter handle non-constant smoothing lengths of SPH particles for the interpolation? If so, how is this set? Due to the nature of the object I'm trying to visualize (a star), the smoothing lengths varies over a few orders of magnitude. Thank you for any help, Carola
