Hi every one ....i am trying to simulate a mixer that contain glass beads with impeller in the middle through LIGGGHTS. when i run the code and see the result in paraview its shows particles with spaces in between them.i want to see the particles in packed form means with no spaces as we see in real situation,is there any problem with code in LIGGGHTS or its the problem with paraview setting or it always shows like this?Kindly guide me,i am new user of LIGGGHTS. I am very tense about my results.i used different strategies like i increased # of particles nd increased run time as well but problem is still unsolved.

what you see is the point
what you see is the point representation (only the center of the spheres is shown as small dot / pixel)
see http://www.cfdem.com/forums/improving-rendering-output
what you can do instead.

Paticles visulization problem
Thanks richit83 ....
I got the idea of "PointSprite plug-in" ,I made changes like this
{ In Object Inspector - Display" select "Scale by - radius", then push the button "Edit Radius Transfer Function" and finally select "Proportionnal" instead "Use scalar range".}
but the problem is that when once i select the files from LIGGGHTS and push the apply button and then i make these changes then the apply button is not available to apply again ,i mean i can't apply the setting of PointSprite plug-in.
kindly guide me .I am suffering for last two months due to this problem.
I also used the idea of Glyph in this way
In Glyph properties:
Scalars radius
Glyph type Sphere
Radius 1
Scale Mode Scalar
Set Scale Factor 1
now i don't know what to write in "Max # of points box" ????
Is this is the total number of particles ??
when i considered this as total # of particles ,so in my case there are 50000 particles ,when i put 40000 or 50000 in given box its stop works.
please need help in this regards too.
Thanks

50.000 is a little too much
50.000 is a little too much for glyph Spheres even when you own a quattro 4000 gpu...
I didn t unterstand why point Sprite doesn't work what is the exact error Message?
Can you update to pv 5 and use gaussian Repräsentation as suggested in the linked thread?
Good luck
