Maximum Force for Alamode calculation

[zohansyahfatomi]

Dear Admin,

My name is Zohan.
I plan to calculate phonon properties.
In the documentary, it is said that:

After that, please optimize the internal coordinate so that the atomic forces are negligibly small.

How small can the maximum atomic force get reliable results in Alamode calculation?
Thank you very much.

Best regards,
Zohan

Hi,

In many cases, I optimize the atomic positions until all force components become less than 0.1 eV/Å.
