[Pw_forum] elastic properties

[kada galami]

hi
 dear evayz 
i spoke to you earlier in the forum about the elastic properties with ibrav = 0 ( free lattice
i have some questions :

1- we do the calculation of elastic propreties only with ibrav= 0
2- i read about the input ibrav= 0 
we have to put only the celldm(1)
and the cell parameters
where i can get the cell parameter, i think have somthing with basic vectors

thank you in advance for your help
