$currentprecision is the command to set the current convergence criteria. Usually the DDCC program solve the program until the error is smaller than $error. The $error is from the potential error where  \Delta Ec < $error . However, when the currentprecission is set, the program will also request the simulation program to get current density error in each iteration smaller than the $currentprecision.

 \frac{ (J_{i+1}-J_{i} ) }{ J_{i}} < $currentprecision
