Hello, I am very new in calcuating the piezoelectric coefficients for different structures. I read the mailing list in siesta and also the tutorial.
It seems that I have to use the "Polarization Grids" in order to calculate the piezoelectric coefficients, but I am very unsure about the method I have in mind. I would be very thankful if anybody who has the experience of such calculations, let me know what I should do in brief. Regards, Hiva
