Re: Separate converging of long- and short-range parts of ma

Dear Samuel,

Thank you for your answer. I will try without splitting, though running the short-range part on the same mesh as the long-range one scares me a bit.

Best wishes,
Petr

Separate converging of long- and short-range parts of matrix

Dear all,

The EPW has a feature of using different meshes for long- and short-range parts of
the electron-phonon matrix, but is it possible to use this feature
for solving iterative BTE? What the input in this case should be?
Will be grateful for reference to any example.

Best wishes,
Petr

Re: Wrong VBM and CBM in mobility calculation

Dear, all I've got similar problem, but in my case increasing number of q-points (from 6x6x6 to 8x8x8) helps. If plot interpolated bands on the coarser grid than there is an artifact near the VBM that causes the issue. Here mesh is 12x12x12, so probably it is not the case, but plotting interpolated ...

Re: Error in routine readwfc

Hi, jghuang, I don't get where did you changed the unit. I ment to change it inside readwfc.f90 in the sense that instead of all iuwfc put some hardcoded number. As for DIRECT_IO_FACTOR, for sure, it is platform specific, the best way is to use inquire statement, something like this inquire(IOLENGTH ...

Re: Error in routine readwfc

Teng, I Have the same problem with readwfc at cluster. Have not try if it related to starting nscf calculation before epw, but currently fixed it as follows: 1. Initially the fall was at the call of OPEN statement (readwfc.f90 line 57), seems something is wrong with the unit 'iuwfc', the fix is to ...
