Re: efield vs. dpwr, field definition --> follow up on old thread

Hii

Iam in the initial stages of learning MPB tool.
My work is mainly focused on band gap tuning. 
I tried to change the radius every time  before I simulate and find the
band gap but as Iam dealing with 3-D structures,its consuming a lot of
time like 4 to 5 hrs for each simulation to run.
 Can anybody suggest me a method  to find the radius of the triangular
lattice photonic crystal for a particular band gap using some kind of a
loop???


Thanks,
hyma
