Collision Feature ?

[gacarita]

Hi there,

I would like to know if this package is capable of solving collision events between particles. For example, in rubble piles and asteroid formation.

Sorry that rigid body collision event is not supported by now.

However, you can hack the code by inserting the collision detection algorithm as a background force. In more detail, the "background force field" function can do the following things:

• find particles that close enough to this particle
• determine the collisional acceleration
• assign the particle acceleration
