Density of state for a gapless system
Dear Fleur developers.
I have some problems with reproducing the density of states of a gapless system.
I already increased kpoint mesh to 36x36x36 and reduce sigma to 0.002 and do a test with the tetrahedron method
/bzIntegration/@mode tria But I still fail. Do I need to increase higher k-mesh, or any other ways, because increasing kmesh option may not meet my cluster abilities.
I included below the DOS, bands.
Thanks for any help.
