Error in binning

Submitted by Joel Martis on Sat, 03/12/2016 - 09:45

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

Dear richti 83,

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,
Limone
