Hi I have a orthogonal Cartesian grid in which the value of epsilon is set on each grid point for diamond lattice. I want to import this into MPB. But it seems that I must convert my whole grid into non-orthogonal grid which is used in MPB, assuming these are the basis vectors:
(set! geometry-lattice (make lattice (basis-size (sqrt 0.5) (sqrt 0.5) (sqrt 0.5)) (basis1 0 1 1) (basis2 1 0 1) (basis3 1 1 0))) Could you please help me how I can import such data into MPB? Thanks Setareh
