[lammps-users] Errors:Bad principal moments

Hello,I came to the forums looking for some help.
When I introduce my input script into lammps,I am getting an Error: Bad principal moments.
The mannul describes the error as follows:Fix rigid did not compute the principal moments of inertia of a rigid group of atoms correctly.
Please help me solve this error.
Thanks.

You'll have to post more information, like your scripts. For
as simple and small a problem as reproduces the problem.
Does it happen on the first time step? If not, then you
are likely doing bad dynamics.

sorry, but my crystal ball is currently in repair
and without one of these it is impossible to see
what you are doing that causes it.
