Your calculation of c11 looks good. A good prediction of c44 tends
to be more difficult. But anyway, the purpose of a theoretical calculation
is not the prediction of an experimntal property. The purpose is learning
what influences the property. Is temperature? Is pressure? Is the xc
functional? You determine that by: (1) reading and understanding the
literature available on your system or your calculation method, (2) modifying
the parameters of your calculation, (3) trying to be in contact with the
main authors developing your available codes.
Week end (saturday and sunday) is not a working day for most people,
even though workaholics like myself can be found. Expect more answers
on monday.
