Dear VASP Masters and Users,

While running a calculation with vasp.4.6 (either parallel or serial), the message "hit a member that was already found in another star" appeared lots of times. Could you please tell me what does it mean, and what could be the reason?

Thanks.

More info: This has something to do with symmetrizing the charge density in the rec. space (subroutine RHOSYG, in symmetry.F), and happens only (?) with body-centered tetragonal (bct) structures. I still don't know why!

This message usually only occurs if the unit cell has very strange shape.
Please check the symmetry information part in OUTCAR.

Thank you very much. Choosing the lattice vectors and basis as suggested by VASP would solve the problem.

Is the calculation wrong when this message occurs?
can I ignore the messarge ?
Thank you!

usually, for reasonable lattices (Bravais matrices) , this warning does not show up, it indicates usually that the angle between 2 lattice vectors is close to 0 or 180 degrees.
Please only continue if you are sure that your cell geometry is correct.
Of course, vasp will continue to calculate with that lattice as usual.
