Error: lost atoms

Submitted by marc on Fri, 12/16/2011 - 12:21

Hi There,

I'm having a problems when running my simulations. The following error happens:
ERROR: Lost atoms: original 1976 current 1971
I have tried to change some parameters like reducing the time step, reduce the entry surface size and so, but I couldn't find out what causes this problem.
The case is simple, it is a box in the top of a conveyor. I'm using particles distribution from 60 to 250 mm diameter.
I'd appreciate any help about what could cause this problem.
Best regards,
Marc

Is the loss of particles "naturally" or by simulation divergence?
In the first case, there are two possibilities:
You can set your boundaries so that they encompass all particles at any time, see "boundary" command.
Secondly, if you "loose" particles intentionally, you can turn off the lost atoms error via "thermo_modify"

Cheers, Christoph

Thanks Christoph,

Yes, I loose them intentionally. I'll turn off the lost of atoms error via thermo modify.

Best Regards
