Strange Particle disappearance and re-appearance behaviour

Submitted by RocheDEM on Tue, 10/09/2012 - 18:00

Not too sure what is going on here... When I look at my results in Paraview, I have particles that disappear and re-appear. I use the v.manyGran() method to create the vtk files.

It looks like I have particles that are at rest that are just vanishing and coming back. I think that it is simply a display issue, I think that the particles are always there, but that they are just not displayed all the time.

Could it be due to my dummyfile format?

All the pertinent files are attached.

Thank you,

Kirk

For the glyph in paraview, there is a default maximum set to "5000". if the # particles exceed that limit, you get exactly the behaviour you describe

What would be a better way of showing the particles when I have over 5000? Can simply just increase the maximum # particles for the glyph? Or do I need to show the particles with a different method?

Or you can use Point Sprites instead on the glyphs - that additionally gives you higher rendering speed
