SUMMARY
The K-point mesh and Monkhorst-Pack method are closely related concepts used in VASP (Vienna Ab-initio Simulation Package) for electronic structure calculations. The Monkhorst-Pack mesh is a specific type of K-point sampling that provides a regular grid in the first Brillouin zone, which can be adjusted based on the number of cells in the simulation. As the number of cells increases, the Monkhorst-Pack mesh may increase, while in some cases, the K-point mesh may decrease, reflecting different sampling strategies in computational studies.
