Hello,
im modeling an continous mixer and have two different particle types.
I continously inserte particles at two different location and the mixed up particles leaving the mixer at the same place.
Now the problem. Because of the continously use, there are build more and more particles.
Is it possible to delete all particles, which are at the same area (exit of the mixer).
I have tried it with the delate_atome command and wasn't very successfull.
If anybody can help me. I would be very grateful.
Best regards
RobertG

fix massflow/mesh has an option for that
^see manual doc/fix_massflow_mesh.html
delete_atoms value = yes or no
yes = to remove the particles that pass through the mesh surface
or you make a region where the particles should dissapear and than:
run ${runsteps} every ${delete_steps} "delete_atoms region clear" but this interrupts the run and leads to longer simulation time ...

Hm,
Hm,
maybe I should be more precise. The particle don't move through an .stl-wall.
There is an opening in the .stl-wall, which they falling through. The real problem is:
I'm getting the error message :
*** Process received signal ***
Signal: Segmentation fault (11)
Signal code: Address not mapped (1)

[ 0] /lib/x86_64-linux-gnu/libpthread.so.0(+0x10340) [0x7f981f0f1340]
I belive that my be caused, because the particle leaving the "create_box"-region.
I will try your second suggestion and post the results.
Thanks a lot.
Best regards

you could also create a stl
you could also create a stl surface where you have your hole and use it as a non wall mesh where you track your mass,
