[DFTB-Plus-User] Troubles with DFTB+ 18.2 MPI (EXIT CODE: 7)

[Daniele Selli]

Dear DFTB+ users,

I am using the MPI version of the dftb+ 18.2 code on an intel cluster
(running on more nodes).
The system is pretty big (around 2000 atoms) and I am also using
the D3 module for dispersion forces.

The problem is that, randomly, I have the following error:
.....
.....
***  Geometry step: 0

 iSCC Total electronic   Diff electronic      SCC error

Did some of you ever experienced the same error?
Thank you so much for your help.

All the best,
Daniele
