-it meets the BCs and zero-div, is controllably smooth, and excites modes with all symmetries. ​+it meets the BCs and zero-div, is controllably smooth, and excites modes with all symmetries. It would probably be better to work the length scales Lx,Ly,Lz into the exponent of ''​(1-smoothness)'',​ so that the variations in the random field are roughly spatially isotropic
