What do you need before DFT calculates the project??

Update Date: 2026 Year 6 Month 27 Day

1. Write scientific questions first

Don't just write "do the DFT.". Should indicate whether you want to be more stable, absorbent, reactive, electronic, defective, or interface charge transfer. Scientific issues determine models, methods, calculations and modes of delivery.

2. Preparatory structure and system information

To the extent possible, provide CIF, POSCAR, XYZ, Gaussian input files or reliable documentation structure, with information on crystals, commingling points, defects, coverage, solvents, temperature and charge status, etc..

3. Identification of subjects for comparison

List all materials, adsorbents, paths, bits and control groups. The calculation is usually determined jointly by the "Structural Quantity x Methodological Level x Analysis Items".

4. Clarifying results and delivery

Description of need for optimization of structure, energy meters, DOS/PDOS, energy bands, differential charge, Bader, COHP, transition state, frequency, freedom of correction, chart and textual interpretation.

5. Availability of references and time nodes

References help harmonize models and parameters. Time nodes should include mid-term inspections and final deliveries, avoiding significant changes in the range of calculations as contributions approach.
