Apr 7, 2022 · NELMIN specifies the minimum number of electronic self-consistency steps. It is rarely necessary to change the value of the NELMIN tag.
Without setting a delay VASP will probably not converge or at least the convergence speed is slowed down. NELMDL might be positive or negative. A positive ...

Who owns VASP?
VASP is copyright-protected software. The copright owner and sole distributor worldwide is the VASP Software GmbH, having its place of business in Vienna, Austria, represented by Prof. Dr. Georg KRESSE.
What is VASP used for?
The Vienna Ab initio Simulation Package (VASP) is a computer program for atomic scale materials modelling, e.g. electronic structure calculations and quantum-mechanical molecular dynamics, from first principles.
What is virtual asset service provider VASP?
Virtual asset service providers, or VASPs, are entities that carry out exchanges between different forms of virtual assets or between virtual assets and fiat currencies.
What is the conjugate gradient method in VASP?
The conjugate gradient method requires a line minimization, which is performed in several steps: First a trial step into the search direction (scaled gradients) is done, with the length of the trial step controlled by the POTIM tag. Then the energy and the forces are recalculated.
