Hello Larissa,n For simulating flow through twin-screw extruder, mesh superposition technique (MST) will be applied. You may want to refer to polyflow example 38 Twin screw extruder, for more details.n You can download the polyflow examples from ansys help site: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/prod_page.html?pn=Polyflow&pid=Polyflow&lang=en&prodver=20.2n Hope this helps.n Thanksn Yin
