segmentation fault

Hi all,

i'm trying to reproduce a rotary kiln with two different form of particles, rectangular and spherical,
my problem is that when I try to change the neighbor from nsq to bin it gives me a segmentation fault,
I've saw that the problem is probably related to the neighbor bin, which I have to select when I add triangular meshes. Someone knows how to solve this?

Regards,

Not totally sure I understand your setup, but are you trying to insert the baffles after you've already generated particles? If so, are you certain that the baffles aren't being inserted in such a way that they intersect with existing particles, which would cause a blowout?

Regards,
Chris

no i'm pretty sure this doesn't happen, because i've tried without the mesh and it gives the same error:

Hi Riccardo,

seems you are using an old version of LIGGGHTS. Please try with 3.X and let me know if the error persists!

Hi Cristoph,

that was my fault, I didn't saw that there were some particles in my data file who had the same coordinate of the mesh, I didn't realize it immediately because my mesh is a bit complicated,
thanks for the asistance,
Riccardo
