Hello users

I am trying to recompile vasp with spin spiral options. I did a search on the forum but was unable to find any solution.

In the makefile.include, I have included -Duse_enini_without_ldelay and recompiled. The compilation was finished without any error. However, when I run the spin spiral calculations with appropriate tags, I don't get any results related to spiral spin calculations. Do I have to add anything extra in the makefile during the installation? Any help will be appreciated. thank you.

Hi scant_centre,

Just to make sure, are you compiling and running vasp_ncl? That will be essential.

Otherwise, could you please share more details, e.g., attach the makefile.include and a minimal example of the kind of calculation that you want to run, give the VASP version etc.

Best regards,
Marie-Therese

Dear Marie-Therese

Thank you for your reply. Yes, I have compiled and tried vasp_ncl. I have attached the makefile.include and I am using the vasp 5.4.4 version. I am trying to reproduce Fig. 1 in the following reference.

Marsman, M., and J. Hafner. "Broken symmetries in the crystalline and magnetic structures of γ-iron." Physical Review B 66, no. 22 (2002): 224409.
(DOI: https://doi.org/10.1103/PhysRevB.66.224409)

Thank you once again. regards.

Hi,

At the moment it is difficult to help you without knowing more details how you proceed. If you have not yet done it, I suggest that you first run a few non-collinear cases from the test suite just to check that your executable vasp_ncl is ok. If you go in the directory VASP/testsuite/tests/ and do "grep run_vasp_nc */runrecipe.sh" you can see which tests are using vasp_ncl. The results that you obtain should be the same as the ones in OUTCAR.ref.

Hi scant_centre,

Could you please attach a minimal example and describe what is not working. Then, I will test if it runs correctly in my setup and we can figure out how to fix it in your setup.

Best regards,
Marie-Therese

Hi Marie

The issue has been fixed. There was some problem with my complier and I was able to fix it.

Thank you.

That's good news! All the best for your calculations.
