Hi dear administrators and experts
hope you are doing well
i have a problem in the calculations the process stopped suddenly without a crash file or error the scf and nscf are calculated well but in the beginning of the wannierization its stopped

Code: Select all

     Spin CASE ( default = unpolarized )

     Initializing Wannier90

Note: The following floating-point exceptions are signalling: IEEE_DENORMAL

this is what i get in wout

Hi ilias-serifi,

I think, you will get better explanation about your problem from the Wannier90 community if you communicate with them.

If you would like to share your input files, I can still see it in more detail and try to figure this out if you want.

Best,
Hari
