### Solve anisotropic Eliashberg equations

Posted:

**Sun Oct 10, 2021 5:44 am**Hello administrator:

Recently,i had a problem with Solve Anisotropic Eliashberg Equations, where no error file was reported after an interrupt to the calculation process and got stuck in the output line below. What could be the problem?

and the input files is :

Ihad try to change the "max_memlt" When I came across this problem ,But it's not this parameter. So how can I solve this problem,Thanks you ! Best wish!

Ihad try to change the "max_memlt" When I came across this problem ,But it's not this parameter. So how can I solve this problem,Thanks you ! Best wish!
