[QE-users] Help !. Relaxation 2D material with assume_isolated="2D" no work

[Wilber Muriel]

Dear,


If any quantum espresso users in the past were able to use the assume_isolated 
="2D" option successfully to relax 2D materials, could you tell me what version 
of QE you used?


I am trying to perform some calculations using the assume_isolated ="2D" 
option, and I have problems relaxing a 2D system, the forces do not converge, 
they always oscillate around a value, I have tried several options for 
ion_dynamics ('damp', ' fire','bfgs'), and the result is the same, the forces 
do not converge. When I try to perform the relaxation without the 
assume_isolated ="2D" option, the material relaxation can be performed 
successfully. The version of quantum espresso used is 7.2 develop commits- 
6b20a77d4714ce6e20d1e22cb05a9cb8a56e5328.

Attached my input file and output file.
