SUMMARY

The K-point mesh and Monkhorst-Pack are not the same, although they are related concepts in the context of VASP (Vienna Ab initio Simulation Package) calculations. The Monkhorst-Pack scheme is a specific method for generating K-point grids, which are essential for accurate electronic structure calculations. As the number of cells in a simulation increases, the Monkhorst-Pack grid may increase in density, while in some cases, the K-point mesh may decrease, depending on the specific requirements of the simulation. Understanding these nuances is crucial for effective materials modeling using VASP.

PREREQUISITES
  • Familiarity with VASP (Vienna Ab initio Simulation Package)
  • Understanding of K-point sampling in electronic structure calculations
  • Knowledge of solid-state physics concepts
  • Experience with computational materials science
NEXT STEPS
  • Review the VASP documentation on KPOINTS for detailed guidelines
  • Explore the implications of K-point density on simulation accuracy
  • Learn about alternative K-point sampling methods

TL;DR
I am confused as how these are used in VASP calculations
Are the K-point mesh and monkhorst pack same. I was reading research papers using VASP and in some papers as the number of cells increases the Monkhorst Pack increases but in others the K-Point mesh decreases.
