ABINIT Discussion Forums

Dear abinit users,
I need your help.
I work on DFT+U lesson in abinit. There are two primitive cells in my conventional cell(BaMnF4: space group Cm c 2_1 (# 36)).
firtsly I run tudet_1.in and tudet_1.files. Then I used symrel values of tudet_1.out file in tudet_2.in file. when ı run tudet_2.in and tudet_2.files, it give me errors as "Largest error (above) is so large (0.01) that either input atomic coordinates (xred) are wrong or space group symmetry data is wrong. Action: correct your input file." How can ı overcome this problem. I attached tudet_1.in, tudet_2.in, tudet_1.out, tudet_2.out and tudet_2.log files.

thank you in advance

Dear,
I've replied to your post in the other post you made about that:
viewtopic.php?f=7&t=4277&p=12710#p12710

Could you please avoid to post two times the same question on different part of the forum? This is messing up the forum and the search in it while you'll not get better chance to get a response...
Thanks!

Best wishes,
Eric

Dear Eric,

You are right. Both posts are the same too. Because my first post was not seen on forum, i thougt that ıt was not submit and i sent this post.

Hi everybody,
I am doing the DFT+U calculation for a material with 4 types of atoms and the first atom's U is obtained. When asked to break symmetry, I am told to give the symmetries by treating the atom as a different entity. I want to know how do they do this? And the about vshift parameter also. The k point mesh is 8x8x8 and it is FCC. Can anyone please help me with the solution?
Thanks in advance

Dear Sai krishna,
Which calculation are you doing exactly, I do not understand what you are asking for (" I am told to give the symmetries by treating the atom as a different entity")?
Best wishes,
