Dear LAMMPS users, During the simulation of pouring particles in a box, I have faced a problem regarding neighbor bins. The error showed in the windows cmd is: “Cannot use neighbor bins - box size << cutoff”. One of the atoms has a diameter 1000 times larger than the smaller ones. I have included some portion of the code in the email. Any kind of help or suggestion is apprec…

Dear LAMMPS user, The Martini Research Group at UC Merced has an open and funded PhD position in mechanical engineering/materials science with focus in computational modeling of materials starting this Fall. The research focus is application of multi-scale simulations and measurements to understand fundamental mechanisms underlying tribological phenomena. If you have any questions…
