Improving the rendering of output

Submitted by Joel Martis on Thu, 03/03/2016 - 15:36

Hi all

I am using ParaView to view LIGGGHTS dump files after converting to vtk format. However, the rendering is not so good, as I see only the centres particles. How can I change this, so that I can view complete particles? (I have attached an image showing what I mean)

Thanks,
Joel

I read through your tutorial and I seem to get an error while setting 'scale by' to radius in the 'Display Tab'. The error is:

ERROR: In /home/openfoam/OpenFOAM/ParaView-4.1.0/VTK/Rendering/OpenGL/vtkOpenGLProperty.cxx, line 231
vtkPointSpriteProperty (0x44e47c0): Shaders are not supported by this context.

I tried to use point sprite to visualize a bidisperse packing but failed to show the smaller particles. Is this approach only applicable to monodisperse systems? Is there any good way to export a sphere packing generated by LIGGGHTS into .stl files? Thanks for your help!

I solve the first problem by unclicking the "use scalar range" tab.
Still open to any suggestions on exporting solid packing to stl files... thanks!

Hi everybody..

For ParaView 5.0.0-RC1 PointSprite is no longer available (except you compile it yourself). But there is a new approach
Choose Point Gaussian
under the Point Gaussian settings choose:

  • Gaussian Radius 1
  • Check Use Scale Array
  • Select radius for Gaussian Scale Array

Works like a charm. :-)

I can't seem to find the Point Gaussian plugin. Is it something I need to install myself?

You need a proper OpenGL Display driver (when you own a NVIDIA card: disable nouveau and install nvidia proprietary driver, when you own a radeon card or using mesa driver on a cluster I can't help you, ask the paraview mailing list)

Hi All
How do I visualize the particles in 2D? I try with clip in paraview but it doesn't give what I mean. At a particular instant of time I want to see only particles at that plane only.

Can anyone tell me ?

You can use two clips. For example when you want to clip in Y-direction use clip1 0/-0.01/0 and attach a 2nd clip to this clip use 0/0.01/0 and enable [x] Inside Out.
Or use a calculator-filter expression: coordsY and attach a threshold filter with "Scalars"=Result (of calculator) and min/max=-0.01/0.01.
