Error in binning

Hello all,

I'm trying to simulate heat transfer in a packed bed. When I reduce the simulation box dimension and particle size, I get the following error:

ERROR on proc 0: Too many neighbor bins

Does anyone know why?

Thanks!
Joel

You need to adjust the

You need to adjust the neighbour-bin size with neigh_modify to be 2*r_max.

I have the same problem:
Step Atoms KinEng rke Volume 1 10000 0.0028224575 0 0.0328896 1000 10000 0.008862297 0.00049115792 2.6506716 ERROR on proc 3: Too many neighbor bins (../neighbor.cpp:1776) ERROR on proc 1: Too many neighbor bins (../neighbor.cpp:1776) ERROR on proc 2: Too many neighbor bins (../neighbor.cpp:1776) ERROR on proc 0: Too many neighbor bins (../neighbor.cpp:1776)

What does it mean exactly what you wrote "neigh_modify to be 2*r_max" ?

In the manual I can see some example on how to use neigh_modify.
But what does 2*r_max refer to in this list of examples ?

neigh_modify every 2 delay 10 check yes page 100000 neigh_modify exclude type 2 3 neigh_modify exclude group frozen frozen check no neigh_modify exclude group residue1 chain3 neigh_modify exclude molecule rigid neigh_modify delay 0 contact_distance_factor 1.5 neigh_settings neigh_settings 0.1

Best regards,
