POLYFLOW: Efficient Polymer Processing and Glass Forming
POLYFLOW is an advanced general purposed finite-element-based CFD software product for the analysis of polymer processing and glass forming. POLYFLOW is particularly well-known for its extensive library of viscoelastic fluid models. Thanks to its unique inverse die design capability, customers around the world are able to cut dies much faster than with the traditional build-and-test method. This translates into substantial cost reduction and time savings. Most importantly, the quality of the blown and thermoformed products is greatly improved by running trial and error processes with POLYFLOW rather than on the production line.
Customers have reported dramatic return on investment by introducing CFD modeling with POLYFLOW into their design processes. The following examples illustrate what POLYFLOW can do for you.
Product Features
POLYFLOW offers a wealth of advanced features, such as complex rheological models (including the widest suite of viscoelastic models in commercial CFD software today), very large free surface deformations (using the arbitrary Lagrange-Eulerian (ALE) technique), contact detection, native fluid-structure interaction (FSI), and a unique mesh superposition technique (MST) to simulate the flow surrounding twin screw extruders or overlapping impellers.
An easy-to-use interface and expert system guides the user during the problem setup and through the solution phase. Advanced postprocessing is delivered by FIELDVIEW, the default postprocessor of POLYFLOW, which is embedded in the product.
Simulation Examples

- POLYFLOW has been used extensively in the polymer processing industry for applications that include extrusion, co-extrusion, blow molding, thermoforming, fiber spinning, coating, and single and twin screws extruders. In the glass forming industry, it is popular for fiber drawing, gob forming and falling, and blow molding and pressing. POLYFLOW is also used throughout the food processing industry for mixing, extrusion, and pouffing and for applications in the metal and ceramic industries as well.

Customer Testimonials
“With the first commercial plant in Carrington up and running we're talking about $ 1,000,000 per year that we save... By improved processing, Shell also managed to maintain product quality.”
“The die/mandrel design developed through the modeling techniques demonstrated their invaluable need by boosting production rates as high as 167% and decreasing waste and set-up time 18 fold respectively.”
