I think the example may need adapting for newer VASP / Wannier90 versions. As a quick solution, you can add

Dear Sir,

I have solved the issue regarding the path, now it can write inputs / outputs in build folder. But it is not able to write wannier90.mmm file and showing error like "kmesh_shell_fixed: B1 condition not satisfied"

I am a new user of Z2-pack and I am trying to reproduce the example of Bi given here. Kindly help me to solve this issue.

Here I am writting the log files and wannier90.wout

Here I am sharing the build folder also.

Looking for your kind reply.

Dear Sir,

Thank you very much for your kind reply. But I already have CHGCAR file here in the folder Z2-pack_MoS2. I have created the CHGCAR file via SCF before Z2-pack.

Here I am sharing the Z2-pack folder. Please let me know how will I do it.

In between, what will I write instead "$VASP"? Here I have attached my .sh file also.

Thanks & Regards

Dear Surasree Sadhukhan,

From the error you posted, it seems that the 'CHGCAR' file is missing in the 'input' directory. This should be created in a separate VASP SCF calculation (independent of Z2Pack). Maybe the SCF step was not executed, or there was an error during its execution?

Best regards,

Dominik Gresch
