About Collision simulation

My simulation involves collisions between multiple objects. Regarding the SPH and Chrono in the RigidAlgorithm option, I tested them separately, and either of the two options was used to simulate a single rigid body. There is no problem in simulating a single object at all.

I would like to ask if the collision between multiple objects is involved, can it be done using the SPH option? Or do I have to use Chrono?

Thanks to anyone who gives me replies and suggestions!!!

Best regards!

  • For collisions between objects you have to use Chrono

    More information in XML_CHRONO.pdf in doc/guides

  • @Alex OK, thanks for your apply very much. I known how to use Chrono, but I recently found that I can reproduce the DKT phenomenon using the rigid body SPH method, so I am wondering whether to use Chrono. Your reply solved my confusion, thank you very much.

  • Interactions between objects using SPH rigid algorithms are not based on any accurate approach following solid mechanics.

    While Chrono implements DEM interactions considering properties of the materials such as Young modulus, Poisson ration, restitution coefficient and friction coefficient.
