Spin-orbit coupling in VASP.4.6.31

Message

I would like to include spin-orbit coupling in my calculations and I put LSORBIT= .TRUE. in the INCAR file. However, the program stops with the message 'ERROR: non collinear calculations require that VASP is compiled
without the flag -DNGXhalf and -DNGZhalf'. ' If I remove these flags and recompile, I find the same error message. Can someone advise me ? Thanks in advance !

Best regards,
Marko

I realize that I should have used command 'make clean' before recompilation. Anyway, this forum seems to be very nice!

Hi, I have the same issue. How did you manage to delete the flags?

Hi!

Please note that this thread is ~14 years old, the original poster will most likely not reply. Which version of VASP are you actually using? In newer versions (starting somewhere from 5.2 to 5.4) it is not necessary to set any of the flags -DwNGZhalf, -DNGZhalf, -DwNGXhalf or -DNGXhalf manually, they will be set automatically by the makefile when building the targets std, gam, or ncl. Also

Code: Select all

make clean

has been replaced by

Code: Select all

make veryclean

which completely removes the build directories and will provide the best way to start building from scratch.

Best,
