Particle blast method (PBM)

Hello,

I am new at LS-Dyna and I wanted to perform a simulation with the Particle Blast Method (PBM). My questions are:

1. Has someone experience with this method? Could you share a tutorial or a simple example (keyword-file) for the particle blast method?
2. How could I postprocess these simulations? I wanted to extract the pressure development at specific positions in the air.

Thanks and kind regards,
