Lambda does not converge

General
1

Dear experts and users,
In my EPW calculations, I found that the lambda only converged when degaussw was set to around 0.8eV. When degaussw is below 0.1eV, lambda does not converge properly even when increasing to very large nkf and nqf (values above 100,000). Can you tell me how to solve this kind of problem?
Thank you.
Best,
Adam

Hi Adam,

Can you say what is the value of fsthick in your calculation? A recommended value of degaussw is fsthick/4.

Happy EPWing,
