選擇 ELK (FREE) https://elk.sourceforge.io/ The ELK code An all-electron full-potential linearized augmented-plane wave (LAPW) code with many advanced features. Written originally at Karl-Franzens-Universität Graz as a milestone of the EXCITING EU Research and Training Network, the code is designed to be as simple as possible so that new developments in the field of density functional theory (DFT) can be added quickly and reliably. Or WIEN2k ($500) https://www.wien2k.at/ The program package WIEN2k allows to perform electronic structure calculations of solids using density functional theory (DFT). It is based on the full-potential (linearized) augmented plane-wave ((L)APW) + local orbitals (lo) method, one among the most accurate schemes for band structure calculations. WIEN2k is an all-electron scheme including relativistic effects and has many features. |

MS有版權(quán)? CASTEP(吃?xún)?nèi)存吧。。)小體系跑跑,dmol3 可以分子軌道 (有些精度相對(duì)低)。 開(kāi)源的大眾軟件也挺多哈! quantum espresso ELK (樓上已經(jīng)推薦) Abinit 各有優(yōu)缺點(diǎn) 還有python的PySCF????(名字不知道有么有對(duì)) GPAW(丹麥大佬開(kāi)發(fā)的,手冊(cè)齊全) 要錢(qián)的 VASP(網(wǎng)上一大把。。不過(guò)還是支持購(gòu)買(mǎi)) WIEN2K(全電子類(lèi)型,,手冊(cè)不友好?) |
