dos range

[dwh]

Hello everyone,I calculate the DOS of metal supercell. And the range above the fermi energy is small when I set up the Bands above Fermi level of 50. But I increase the integer to 60 or more, and the calculation process is terminated without any results. Now I hope to get the DOS with the energy range -3eV~3eV of the metal supercell.Could you give me some advices.Thanks

You say no results, does that mean it doesn't finish properly, or there is some plot but no good data?

If the former is the case, perhaps it runs out of memory - you should then try to monitor the memory usage while running. If the supercell is very large, you can perhaps run with fewer k-points. Try setting 8x8x8 or something similar just to see that it goes through.

If it finishes but the plot appears to have no values, try to zoom in. Sometimes the DOS contains a huge value at the lowest energy point, which makes a weird vertical scale.
