[Wien] the puzzle elastic constant

[zhgh at theory.issp.ac.cn]

Dear all users,
   For fcc-Al(a=b=c=4.05ang,RMT=1.7),I calculated its elastic constants
C11,C12 and C44. Our results were C11=62.9,C12=66.2 and C44=36.0(The
unit is GPa),though the experiential values are 107,61 and 28 (The unit
is GPa),respectively. We adjusted a lot parameters such as RMT
,K-point,EMAX and so on,but the results were far away from the
experiential values.
   Please all you help me solve it . I will thank for your any help!

                                            sincerely,
                                             Zhong
