Hi,

I am trying to model the breakup of inert particles when impacting with walls in a user defined boundary condition (DEFINE_DPM_BC). Is it possible to make two or more particles from one single particle after an impact? I know that the particle's id is the pointer *p, but how can I create new particle ids?

Until now, I am only able to change the particle's diameter and velocity components and save the number of particles in a parcel in a user defined scalar. The problem is, however, that the particles in this parcel follow the same trajectory.

Thanks in advance

Hi Seppl
I've read your comment and understood that you know how to allocate some particles in a parcel.
i'm working on a DPM project and I don't know how to assign for example 100 particles to a parcel. Would you help me?
thanks,
