-These figures indicate the principal directions of deviatoric strain. It could be expected, that fibers will orient perpendicular to the shearing direction, if sufficient ammount of flow will be achieved. The principal directions change during the time, as the flow pattern is not stationary. In general, the figures indicate, that fibers become aligned along the walls and along the openings, where the largest shear strains rates are achieved. On the other hand, in the region on the right side, with rather small strain magnitude, the orientation of fibers will not be altered, however, the fibers may have been already oriented, while passing through a area with high shear strains, particularly at the area close to the outlet, alonfg the bottom wall and in the right hand side corner.
