Volume rendering of DPM variable in CFDPost

  Hi
  I have a 3D pipe with DPM particles. I want to see the 'DPM Particles in Cell' using Voume rendering in the whole 3D space. But it is creating shapes similar to the mesh structures which is obstructing the visualisation of the variable. Can i remove the structures or the shapes from the contour plot and get a smooth contour? I have attached the picture below.

  Hello,
  Can you please show the mesh?

  ACtually i want to calculate the variable: N(cell)/A(cell)/N/A and plot it on the cross-section. But it is giving the above issue.

    Yes, sure. But before that, can you please share some images of the mesh?

  The mesh is like this:
  I want a smooth plot of Volume rendering variable.

  Its a O-grid mesh on the cross-section.

  Thanks for the images.
  I see sudden cell jump between the inflation layers and core mesh. Please create smooth transition between the two. Also please note the refinement. I think the mesh is a bit coarse. Maybe you can conduct grid independence test?
  
  Please try to increase the resolution. Did you import the .dat file or did you import some other file?
