EXCITING

Dear all,
with respect to the phase transition pressure,i have run the example BN in both the (zincblende & wurtzite) cases by varrying value of lattice constant.But it is taking too much time (6 to 7 hours ) in wurtzite phase which didn't happen in zinc blende phase. So may i request you to please guide me what changes should i make in the input .in file given below.
