ESyS-Particle

several simulation objects

Asked by Carlos Valdes

Inside the tutorial of the software there is an example related to the formation of sand piles using friction among particles.

It is said that there is no way to directly create friction between a plane and unbonded particles. One solution is to fix the nearest particles of the group (or "cube") to the base plane, in order to those can not go away.

So, the author lefts one exercise to do for ourself, with the idea of not to use the function "BondedWallPrms", and I thought that one way to solve that is to create two more simulation objects:

One for build a lattice of particles, placed under the "cube". It has no gravity and friction among particles is already implemented, and a...

Second simulation object which should be part inside the "cube" and part inside the previous object. This new simulation object would be useful just for generating a spatial domain where friction exists, but any particle is directly related to it.

Therefor, I don't know whether it is possible.
Whether it is possible to create more than one simulation object, whether it is possible to create a simulation object inside of another and whether particles can be inside of two simulation objects at the same time.

Thanks a lot!

Hi Carlos,

if I understand correctly, you want to have a simulation object that does most of the simulation, and you want another simulation object that only works on a small area of the simulation space.

The problem is that each simulation object has its own simulation space, so what you're trying to achieve seems impossible. As far as I know, two simulation objects can't directly interact with each other in any way.

Just to be clear, I am not a developer, so I could be wrong.

Greetings,
Lukas
