SubscriberHello,
Â
I am new at LS-Dyna and I wanted to perform a simulation with the Particle Blast Method (PBM). My questions are:
Â
- Has someone experience with this method? Could you share a tutorial or a simple example (keyword-file) for the particle blast method?
- How could I postprocess these simulations? I wanted to extract the pressure development at specific positions in the air.
Â
Thanks and kind regards,

Hi
We [ ANSYS engineers ] cannot share any files here in this platform. However, may be others might post it if they have.Â
Track the pressure counters, but since air being void most of the method will be limited try to use ALE as it need air domain requirement and then use DEM.Â
It would be best if you get started and then post you issue here than expecting a fully or developed solution here.
check the following studiesÂ
