During analysis, eject some particles

Hello. I’m trying to model the tunnel. So I wanna exclude some particles during analysis. Is it possible to eject the particles?

Do you mean eject in simulation boring into it? It is possible to do so but you have to remove the particles depending on the id. We have had simulations for excavation before.

In the mesh class, we have a function called remove_particles. You could define the particles you want to remove in the entity_set input file as a particle-set, and then do some modification in the code to use the remove_particles function to remove the paritcle-set you defined.
