IERR=0 Error reading item 'MAGMOM'

[bth20]

Hi there,

A noncollinear calculation halted almost immediately with the message:

Error reading item 'MAGMOM' from file INCAR.
Error code was IERR=0 ... . Found N= 49 data.

There are 19 ions in the POSCAR file and it reads that fine. The MAGMOM line is:

MAGMOM = 0.05 -0.05 4.0 0.02 -0.07 4.0 -0.03 -0.04 4.0 0.06 0.01 4.0 0.00 -0.05 4.0 0.00 0.08 4.0 -0.05 0.03 4.0 -0.05 -0.04 4.0 0.06 -0.02 4.0 0.02 -0.04 4.0 -0.07 -0.01 4.0 -0.00 0.05 4.0 -0.03 0.06 4.0 -0.03 -0.04 4.0 0.06 0.01 4.0 0.00 -0.05 4.0 0.00 0.08 4.0 -0.05 0.03 4.0 -0.05 -0.04 4.0

which is 19 sets of 3-vectors in the form which I thought was correct for a noncollinear calculation.

Can anyone see what's wrong?

Thanks

Ben

It could be the line length. Vasp has a maximum line length of 255 char when reading variables from the INCAR, and the MAGMOM line has 294. This can be changed in the drdatab.F file in the vasp library.

Exactly. Set in the drdatab.F file (vasp.4.lib) #define LONGCHAR (at the beginning, bevor #ifdef LONGCHAR) and recompile the lib.

I am having a similar problem but now i have 181 x 3(vector), variable in the magnon line, what should i change in the drdatab.F file?
