ABACUS INPUT parameters for a plane-wave SCF run require setting system variables, file paths, and electronic structure controls like k-point grids and SCF convergence thresholds. Quick example snippets are provided for common workflows.

Setting up the Wannier90 interface in ABACUS requires specific electronic structure controls and projection parameters. You can use the category-indexed parameter guide to verify parameter intent and identify required companion files like orbitals for certain projections.

To troubleshoot SCF convergence issues in ABACUS DFT simulations, use the category links to cross-check electronic structure controls, verify output and restart-loading behaviors, and adjust convergence thresholds according to the structured parameter reference.

ABACUS supports specialized workflows including DFT+U, hybrid or exact exchange, and vdW corrections. The parameter reference details the specific input variables, defaults, and options needed to enable these advanced electronic structure modules.

Relaxation and MD simulations in ABACUS are controlled by specialized input parameters within the INPUT file. The reference guide documents the type, defaults, and options for these variables to help configure and interpret the simulation setup.

ABACUS can be configured for HPC simulations using specialized modules like PEXSI, SDFT, TDDFT, and LR-TDDFT. The parameter guide provides the necessary input settings, types, and defaults to properly configure these advanced electronic structure workflows.
