This is a typical numerical annoyance -- the enthalpy curves of both
phases are shallowly intersecting. And plotting the difference as a
function of pressure is tricky because you don't have the same pressure
grid for both phases.
However, as you have all parameters of the (Birch-)Murnaghan
Dear Wien2k user:
When I set the Ry value from -6 to -13.5 in the wien2k
calculation of Ga(PO3)3, there is always CORE electrons leak out
of MT-sphere. The .in1_st file is below. And the structure file
is enclosed. since in the space group of wien2k, there is no C1c1(9), I

I encountered the following error after generating a new klist:

The klist changed in the course of ‘initso’.

I guess it is a spin-polarized case and SO has reduced symmetry (either
more non-equivalent atoms or at least less symmetry and thus more
K-vector stars).
In principle, symmetso is supposed to handle this situation, but I've
heared before that it does not work in all cases.

I have done spin polarize calculation with spin orbit coupling for YbB6. The

An alternative approach (not well documented in UG, perhaps not

Thanks for your suggestions. Yes, when the Ry is set to be 1.0,
there is no electrons leak out of MT-sphere. all the electron are

What are your sphere sizes.
I got from my setrmt (and your cif): Ga(1.9), P(1.31) and O(1.45).
I have not checked if the distances are ok. P-O distances can be pretty
small, but in any case you should compare the distances listet in
case.outputnn with distances in the ICSD (or in published

the distance is consistent with that in ICSD.
