Shear-induced effects on multi-cavity molds

For multi-cavity applications, the part needs to be meshed in 3D (I used 20 layers of tets through the thickness). Multi-cavity applications require full tet runners.

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

You can see the temperature increases just inside the frozen layer that will enter the part cavities causing certain cavities to fill before others. Depending on the number of cavities and the runner layout, you may even see intra-cavity imbalances like this golf ball application.

Have you ever seen shear imbalances in multi-cavity molds?
