Hello everyone!
please I have a question about the "Trap" boundary condition used by the DPM model.

Is Fluent consider the particle as trapped when:

1) its mass point is coincident with the wall (i.e.the distance between the wall and the particle mass point =0)
or :
2) when the particle is tangent to the wall (i.e. the distance between the wall and the particle mass point = dp/2)

Thank you!
Regards.
