(such as different MeshCutoffs), it will bring about 0.2~0.3 eV errors
artificially.
What about your opinions? Any comment or suggestion is appreciated.

I want to comment that Etot vs Ecutoff is converging very slowly, and
looking at that curve one might want to go as high as 800Ry.

Hi Fei
The mesh cutoff controls the accuracy in the calculation of
some integrals in real space. It is no a variational parameter
in the sense that more accurate does not mean lower energy.
The way to converge it is just by making it larger and larger until
the property you are interested in is co
