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 lid-driven cavity case was designed to evaluate the viscoelasticFluidFoam solver's numerical implementation and computational performance within a simple geometry and orthogonal meshes, without having to deal with issues pertaining to non-orthogonal meshes. The problem is modelled considering the isothermal and incompressible 2D 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.
