Hello abinit users,

I am trying to optimise the electronic structure of wurtzite ZnO. As I 
understand it I need to
optimise the volume and the lattice parameter "u". Is it sufficient to do 
something like this:

optcell 2         # optimise geometry and nuclear positions
ionmov  3
ntime  25       # number of steps
dilatmx 1.05  # ratio change in volume
ecutsm  0.5

(wurtzite structure definition follows...)

Can someone help me with the correct procedure for optimising the lattice 
parameters for a
wurtzite material?  Any suggestions/hints are appreciated.

Thank you.
Best,
   Toby
