Venting analysis is used to predict the effects of air pressure on the flow of polymer to aid in selecting suitable locations where vents may be placed in the mold to allow trapped air to escape the cavity.
The option to perform a venting analysis is available for 3D Thermoplastics Injection Molding, Thermoplastics Overmolding, Reactive Molding, and Microchip Encapsulation molding processes when an analysis sequence that includes Fill or Fill+Pack (using the Coupled 3D Flow solver) is selected.
