[Pw_forum] problem releated to calculating elastic constants

[premlata pandit]

hello
 the experimental lattice constant of Li2S is 10.7867 a.u.
and my calculated equlibrium lattice constant is 10.375 a.u. by using  LDA
pseudopotential in pwscf calculation.
can i use this lattice canstant to calculating  elastic constants?
