Type float
Default 1e-6

Relative convergence of the density:

$\varepsilon = \frac{1}{N} \mathrm{ConvAbsDens}$.

N is the total number of electrons in the problem. A zero value means do not use this criterion.

If you reduce this value, you should also reduce EigensolverTolerance to a value of roughly 1/10 of ConvRelDens to avoid convergence problems.

If this criterion is used, the SCF loop will only stop once it is fulfilled for two consecutive iterations.
