Particle reflection away from boundary

      Hello, I'm using a dpm model.

      Because the dpm model recognizes particles as point particles,

      If the particles are heavy, the distance between the particle and the wall is zero.

      So, if the particle and the wall are separated by the radius distance of the particle, I want to give the reflect bondary conditions.


      Is there anyone who can help?

      Given the particles are "small" compared to the domain and mesh this shouldn't be a problem. If the particles are large, the bigger concern is the lack of blockage to the flow of the particles. You may want to look into the Macro Particle Model.
