Hi,
I am trying to write some code to make unit cell tranformations, so I
have the following naive question about the orientation of hexahedrons
parallelepipeds unit cells relative to x,y axes:
Does at least one "a" unit cell edge start from point (0,0,0) and coincide with
x axis in all hexahedrons parallelepipeds unit cells used in simulations? Do
also the 2 "b" unit cell edges linked to that "a" edge always lie in the xy
plane?

thanks in advance,
Thomas
