exaFOAM Industrial Benchmark B4 - Viscoelastic Complex Profile Extrusion

This work is part of the exaFOAM project, aimed at optimizing the open-source CFD software OpenFOAM for massively parallel HPC architectures and overcoming performance bottlenecks. The viscoelastic complex profile extrusion case was designed to evaluate the viscoelasticFluidFoam solver's numerical implementation and computational performance within a realistic and intricate profile extrusion die geometry, provided by the exaFOAM supporter Soprefa, that represents the typical industrial complexity and scale of the industrial process. Due to the complex geometry employed, the unstructured meshes required to obtain accurate results can easily comprise up to 40 million cells. The problem is modelled considering the isothermal and incompressible 3D flow of a Giesekus viscoelastic fluid. Detailed information and case setup can be found in the README.md file contained in the case setup file.
