This will give to a lm decomposed DOSCAR. The sum of the volume of the spheres around each atom should be the same as the total volume of the cell (assuming that you do not have a vacuum region within your cell). VASP has three levels of parallelization: over k-points, over bands, and over plane-wave coefficients (or equivalently Fast-Fourier transforms). INCAR的简单介绍 作者:elizerbeth 文章来源:[email protected]日月光华.
