Extrusion, mold filling, fiber forming, thermoforming, and coating processes involve complex fluid rheology and deforming free surfaces that not all CFD codes can model. Fluent's CFD software includes powerful tools that are customized to excel for these applications.

Prediction of extrudate shape. Our inverse die design capability allows you to determine the required die lip for a specified extrudate shape.

Prediction of coating flow structure in a two-layer slot coater. Templates allow efficient analysis of alternate operating conditions and determination of stable operable windows.

Blow molding -- Predicted material thickness in a blow-molded part. Analysis provides insight for reducing material use while imposing strength.

Spiral extrusion die -- Temperature distribution in a spiral extrusion die. Modeling reveals how shear heating produces thermal nonuniformity in the extruded material.
