Shear-induced effects on the filling properties

For single cavity applications, the part needs to be meshed in 3D (I used 20 layers of tetras through the thickness). You can use beam runners but only for single cavity applications. Multi-cavity applications require full tetrahedral runners.

I then Edit the material to increase the Absolute Maximum Melt Temperature to 1000 C. I inject fast and have inertia turned on.

You can see the temperature increases just inside the frozen layer that will enter the part cavity causing unique filling patterns (sometimes called “ear flow”).

Have you ever witnessed shear induced filling imbalances in single cavity molds?
