particles containing nan

Hi,
I have filled one cylinder with particles and then i want to insert one big particle on the bed of beads. I use lattice command to do this and apply create_atoms single command, but after that i found "nan" values in output screen. I modified the command many ways, but all in vain.. First I poured particles with pour/dev command and then with create_atoms for inserting single particle. Is there any solution?
Thanks,
Ram

Nan values typically mean bad dynamics and(or bad boundary conditions - maybe you generate the particle(s) in a highly overlapping condition?

Hi chris,
Hi,
Why I can not insert one particle in my simulation box with restart file using create_atoms command? I have created restart file by filling particles in a cylinder with pour/dev command.
Thanks
Ram
