Major new features of this release include pre-defined physics modes dedicated to simulation of non-Newtonian flows, new and updated mesh generation options, and improved graphics performance for visualization of large 3D models.
Simulation of non-Newtonian Flows FEATool 1.15 adds pre-defined equations and a new physics mode for non-Newtonian flows. This allows for easy modeling and simulation of applications with non-linear shear thinning or thickening flow behavior, such as in industrial polymer applications, and biological flows.Non-Newtonian Flow in an Extrusion Diehttps://www.featool.com/model-showcase/04_Fluid_Dynamics_11_non_newtonian1/Mon, 18 Oct 2021 00:00:00 +0000https://www.featool.com/model-showcase/04_Fluid_Dynamics_11_non_newtonian1/This example models flow of a polymer through an extrusion die with two outlets. This type of flow can for example be found in manufacturing processes of plastic parts. The polymer is assumed to be non-Newtonian, and can be modeled with a shear thinning Bird-Carreau viscosity model. The die is also assumed to be rotationally symmetric, allowing a reduction of the model geometry to an axisymmetric cross section.

The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is computed and compared to a reference value.
