Ansys POLYFLOW is an advanced general purposed finite-element-based CFD software product for the analysis of laminar flows typical in polymer processing and glass forming as well as other applications. Ansys 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 Ansys POLYFLOW rather than on the production line. Glass forming and float glass engineering simulation helps the designers to produce higher quality tableware, glass container and flat glass faster than before.

Customers have reported dramatic return on investment by introducing CFD modeling with Ansys POLYFLOW software into their design processes.
