ANSYS designed this TryItNow! experience to give you quick access to ANSYS AIM simulations on the cloud.
This AIM demonstration shows an polymer extrusion simulation of an L-channel. The simulation demonstrates the ease of setting up and solving an extrusion simulation for inverse die design.
Default settings are used to highlight ease-of-use and to demonstrate how AIM automates many of the steps required for the polymer extrusion.
