Image properties of ELF
« on: August 19, 2015, 13:06 »
Sir,
We have generated the cut off view of the electron localization function for our structure but the image of ELF is not clear. Please suggest a way to generate a more clear view of the ELF plot.

Do you have an option to tune the scale of the plot, such as to make the relevant features of the ELF plot more clear?

No sir,
There is no such option which can enhance the picture quality and remove the blurredness.

The resolution of the ELF corresponds to the grid mesh cut-off used in the calculation, so if you increase that, you get more details in the picture. However, there is a trick to getting a picture with higher resolution without recalculating anything:
Code: python
conf = nlread("file.nc", BulkConfiguration)[-1]
conf.calculator().numericalAccuracyParameters()._NumericalAccuracyParameters__grid_mesh_cutoff = 500*Rydberg
elf = ElectronLocalizationFunction(conf)
nlsave("elf.nc", elf)
What this does, is it tricks the program into thinking you actually used a higher cut-off in the calculation. Of course, it's cheating in a sense, or rather, call it an interpolation.
