Using the code at
http://qiita.com/7of9/items/66919d3aed0e651bc6d7
I checked the pvec (polarization of dipoles) for checkpoint time for 20sec.

./adda -grid 25 -chp_type normal -chpoint 20s

Note (Added on Apr.16, 2017): According to [reply in this](https://groups.google.com/forum/#!topic/adda-discuss/f3_Cm3HFtkA), above shown pvecs was not truely the dipole polarization, but auxiliary vectors for the iterations.
