you should find the Radioss example model files in the installation and the example document in Help

Hi,

I assume you are using SPH particles?  I don't think there are any studies about the number of particles available in the help.  It depends on the problem, the speed of the computer you have available to run the simulation, and how long you want to wait for results.  More particles means longer solution times.

I would start with less particles and make sure the simulation is running and that your boundary conditions are correct.  Then you can add increase the number of particles to study how the results change. 

Thanks,

Andy

Hi Rahul, 

Thanks for sharing @Rahul Ponginan .

I've seen this study before. But, unfortunately this is not about the change in the number of particles.

Thanks.

Hi @Andy 

Thank you for information. 

I have asked before in topic: 

https://community.altair.com/community?id=community_question&sys_id=0176443a1b2bd0908017dc61ec4bcb66

• Can we say that as the number of particles increases, the results get closer to a certain value?

And after a certain number of particles, increasing the  particle number wont effect the simulation results? (which is the case for mesh convergence in FEM analyses)

Thank you.
