exaFOAM Microbenchmark MB19 - Viscoelastic 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 profile extrusion case was designed to evaluate the viscoelasticFluidFoam solver's numerical implementation and computational performance in a simplified profile extrusion problem. Due to the simplified geometry employed, the meshes required to obtain accurate results will be much smaller than those of the associated industrial scale case study (B4), allowing to perform initial exploratory studies. 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.
