Key energy-power parameters of an Equal Channel Multiple-Angle Extrusion process, theoretical material flow patterns through a 2-turn rectangular die and dynamics of macroscopic rotation formation in amorphous materials have been determined with a numerical finite-difference solution of the curl transfer equation for planar flow of viscous incompressible continua. Good agreement between theoretical and averaged experimental results was found within the scope of physical simulation.
