$currentprecision

$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 $\mathrm{\Delta }Ec<\mathrm{\$}error$. 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.
