[DFTB-Plus-User] DFTB+ stalled when outputing "Geometry converged"

[xuB.O.A]

Dear all dftb+ users

 

The following screen priinting puzzles me. When i put the input file into calculation with

Cg-method and a maxstep of 100. The error that dftb+ ceased at Step 0 after printing "Geometry converged" occasionally

occurs in the calculation.And i have to press Ctrl+C to quit to the console For i use the executable binary file of DFTB+ into a high throughput calculation. The error of this kind can not be affordable. So i would be very grateful if you could help me.

 

Thx for the attetion.

 

best,
