Rubber Injection Molding

Application ID: 90361

This tutorial shows how to set up a 3D simulation of rubber injection molding. A phase field method is used to track the interface between the rubber and the displaced air. The rubber is modeled as shear-thinning inelastic non-Newtonian power law fluid with a fluid-consistency coefficient resulting in a high ratio between the viscosities of rubber and air. To smooth the large viscosity difference across the interface, a viscosity averaging method based on the volume fraction is used.

This model example illustrates applications of this type that would nominally be built using the following products:
