Dear users,
I am a biginner in WIEN2k_01 code i try to use it in
my work about storage of hydrogene. I have do the
quick start exemple (TiC) and its OK, then a bigun to
study ZrNi and its ok also. But when I do the
calculation of ZrNiH it 's not ok.
Well i have used the Orthorbic structur for ZrNiH (see
the case .struc below), the NN distance is 1.44 so i
have not a greatt choise for Rmt so at first I try for
Zr 0.9 and for H 0.54 but I have the famous warning:
0.506328 core electrons leak out of MT-sphere and also
the warning for good atomic total energies ..etc. of
corse i change the Ecore (between -6.0 ~-10.0) but
nothing.
I try againe to minimise the leak out electron and
the best cobinaison of RMT (Zr H )is
1.19 and 0.25 with warning: 6.58721307987755E-002
core electrons leak out of MT-sphere!!!! and a warning
of H atom good atomic total energies you should
probably change the radial mesh etc... i have continue
the Initialisation calculation and I have change the
Rmt*Kmax to 3.0 and Gmax to 20 (what was suggegested
in mailliste) but i have got Gmin gt Gmax, so i have
changed Rmt*Kmax to 2. it seems ok(Gmax£ gt Gmin).
When I run the SCF excuting: run_lapw -cc 0.0001
LAPW0 END
SELECT -Error
the error in Lapw1.error is :
'SELECT' no energy limite found for L=0
'SELECT' E-bottom -5.96500 E-top -200.0000
I try all the advices found in the mailist,I have
searched the archives but I couldn't solve my problem
that way.
thank you
