Compute the total energy at a fixed geometry using VASP without ionic relaxation.
Create a workflow, supply the structure, and run a VASP single-point calculation to obtain the total energy at the fixed geometry.

To calculate VASP energy at fixed geometry, run a single-point calculation by enforcing settings like NSW=0 and IBRION=-1, which disables ionic updates and evaluates the total energy at the exact input structure.
A true VASP single-point calculation requires setting NSW=0 and IBRION=-1 to freeze the geometry. You can also use optional flags like LCHARG, LWAVE, and NEDOS depending on your downstream analysis needs.
Yes, a VASP single-point calculation is the standard pre-DOS or pre-band workflow step. By enabling LCHARG and LWAVE, it computes the total energy at fixed geometry while generating the charge density file needed for subsequent analysis.
To test ENCUT and k-point convergence in VASP without structural changes, use a fixed-geometry single-point calculation. By setting NSW=0, the structure remains frozen, isolating the energy response to varying cutoff energies or k-point grids.
Run a VASP single-point energy calculation instead of relaxation when you need to evaluate the energy of an already optimized geometry, test convergence at fixed atomic positions, or generate charge density files for DOS and band-structure runs.
