VASP 5.4.4 + Wannier90 3.0: 'Not enough bvectors found' Error Solution

This error message indicates that an issue occurred during automatic selection of b-vectors. The program encountered a small singular value while attempting to use singular value decomposition (SVD). Consequently, it exits with the 'Not enough bvectors found' error, suggesting that sufficient b-vectors couldn't be determined.

To resolve this, you might need to adjust certain parameters. Consider options like manually selecting b-vectors, tweaking the kmesh settings, or increasing the computation time. Consult the VASP and Wannier90 documentation for guidance on modifying these parameters and experiment with different settings to find a suitable solution.
