udf for dpm boundary condition
 

hello CFD forum!

Currently I am trying to define the DPM boundary condition for a wall, where a particle is impinging. The goal is to let the particle move through the wall, as if the wall would be defined as interior. Due to the simulation that I am fulfilling I cannot simply define the wall as interior, I have to implement the described problem via an UDF.

Is there a possibility to define the wall as interior only for an inert particle? I also tried to modify the example stated the UDF manual, where a DPM reflect boundary is presented, however it did not work out.

Thanks in advance for any help!
