Rendering high number of particles in Analyst

Hi EDEM team,

I generated a packing (spheres) with 3.3 million particles, when I opened it in the Analyst, the rendering became extremely slow and I basically could not click on anything. Is there a way to improve the rendering performance? Is it then even possible to render a simulation with ~10 million particles?

The graphics card I used was Nvidia A6000-48GB.

Regards,

Hao

Hi Hao,

In the EDEM Creator > Tools > Options > Rendering Options you should have the option for Legacy display which is slower or Instanced. If you choose the 'Optimised for Nvidia' it should help with the display speed.

Contacts display slowly in the Analyst, if you have selected to display contacts then this does take extra computational effort. You can remove this option if set (or close EDEM, in the simulation folder delete or rename the simulation.dfg file and open again, this resets the display to default).

Otherwise updating the graphics drivers and Operating System (Windows updates) typically helps.

Hi Stephen,

Thanks for the heads up, I changed the settings to Instanced and reset the display to default, now I can visualize it in the Analyst.

Just a quick follow-up, is there a guide for the maximum number of particles for rendering/post-processing, like the post you wrote on the speed test for the graphic cards? It would be nice to know the upper limit of the number of particles (sphere, multisphere & polyhedral) before one actually sends a huge simulation to a cluster.
