"hit a member that was already found in another star" ?

Hi,

I get this message a zillion times in my output:

Code: Select all

hit a member that was already found in another star
It has something to do with symmetry.
Any idea what is wrong with my configuration or is this a bug?

My input files are here:

Probably you should modify your KPOINTS from 1 1 11 to 2 2 11 to avoid this problem - or, more easy, try "Gamma" in the third line of the KPOINTS file, this centers the Grid to the gamma point.

Nope, doesn't seem to help.

I tried this:

Code: Select all

k-points
0
Monkhorst-Pack
2 2 11
0 0 0
and also this:

Code: Select all

k-points
0
Gamma
3 3 11
0 0 0
to no avail. I get this kind of output:

I don't know ... if VASP runs correctly for the rest of the calculation and the energies seem to be reasonable ...

I'll have a look at it. This error usually only occurs if the unit cell is completely distorted (angles close to 0 or 180 degrees). This is definitely not the case for your cell. A quick solution of the problem would be to switch off symmetrization (ISYM=0)
