Review:
Openmx (open Source Sem Tool)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
OpenMX is an open-source software package designed for materials modeling at the atomic level. It enables researchers and scientists to perform quantum mechanical calculations based on density functional theory (DFT), local density approximation (LDA), and generalized gradient approximation (GGA). OpenMX is particularly known for its use of linear combination of pseudo-atomic orbitals (LCPAO) basis sets, which allows efficient simulations of large and complex systems in condensed matter physics, chemistry, and nanotechnology.
