Noise in LOCPOT
Posted: Wed Dec 20, 2006 4:04 pm
For surface calculation, I found that LOCPOT has a lot of noise. If the surface is in the x-y plane, I pick an x and y on the surface and plot the potential along the z direction, I found that there are a lot of fluctuations when the potential is decaying into the vacuum. In addition, it seems like if I let VASP adding the exchange-correlation part into the local potential, the noise is even bigger. Is there any way to improve this situation? Thank you.
