### Re: How to run EPW for calculating the isotropic superconducting properties

Dear Hari Paudyal:

But, I have a problem.
Which file is contained the distribution of the isotropic superconducting gap on the Fermi surface?
Just like prefix.pade_aniso_gap0_XX when I am calculating anisotropic superconducting gap.

Sincerely,

YSW

### How to run EPW for calculating the isotropic superconducting properties

Dear all,

I want to run EPW for calculating the isotropic superconducting properties.
What parameters do I need to set ?

### The number of superconducting gaps

Dear all,

Sorry to bother you again.
How can I know from the graph or dates how many superconducting gaps there are.

Sincerely,

### How to pick the right value of degaussw

Dear all, I have a trouble. In my case, I calculate superconductivity with 10 10 10 k/q grids, and I get a same lambda with 20 20 20 k/q grids.(degaussw = 0.5,lambda = 1.799) but, when I change degaussw,the value of lambda have a big change with 10 10 10 k/q grids.(degaussw = 0.4,lambda = 1.899). Un...

### Re: Mapping the superconducting energy gap on the Fermi surface in BZ

Dear H. Lee：

But,I have to say,I am a green hand.and I have some problems about using this script.

How should I execute this script ?
Need I use Prefix.imag_aniso_gap_FS_010.00 and nscf.out ? If I need, How should I use the date with this script ?

Sincerely,

YSW

### Re: Restarting EPW with finer kf/qf grids

Dear H. Lee:

I just restart the interpolation part, I donot konw whether repeat the evaluation of e-ph vertex ?
but I get a good result.So, is it a successful calculation? even though it is no convergent.

Dear H. Lee：

This image is invisible likely.
So,I provide the link of this image.

### Re: Mapping the superconducting energy gap on the Fermi surface in BZ

Dear H. Lee：

Yes,you are right.But,if I want to limit the image in 1st BZ.
What I need to do ?

Just like this

Sincerely,
