Organizing the Model

The model has to be organized as layers based on the materials.

Layer organization plays a vital role in co-extrusion models.

The term layer is used to denote a coextrusion layer. It is made of solids/parts that form a conduit for each polymer from the inlet to exit. It should be noted that the interface between two layers is an immiscible interface for material flow. In simple words, parts/solids of the same polymer type go into a single layer. There is no specific sequence required to add a part/solid to the layer.

  1. Click the Polymers tab.
  2. Click the Organize icon.
    The model is automatically grouped into layers based on inlet boundary conditions. It starts from each inlet and recursively moves toward the exit, marking all connected solids into a layer.


  3. Select a layer in the legend to make it the active layer.
    Note: Tool Parts are only automatically identified if the user has extracted the flow volume, else they can be added manually.
  4. Click on any solid to organize manually.
    If you hover over a solid that is undefined, the cursor will have a plus sign. Clicking on this solid will add it to the active layer.If you hover over a solid that is already in the active layer, the cursor will have a minus sign. Clicking on this solid will remove it from the active layer and mark it undefined.If you hover over a solid that is in another layer, the cursor will have both plus and minus signs. Clicking on this solid will move it from the existing layer to the active layer.
  5. Right-click on any layer in the legend to create a new layer to add parts to, to reset that entire layer to undefined, or to delete the layer and its part.
  6. Click Isolate next to any layer in the legend to see only its parts, or click All to show all layers again.
    Note: You can organize layers outside of the Organize context by right-clicking on any part and selecting Organize As, and a layer, to add that part to the layer.
