SOD2D, "Spectral high-Order coDe 2 solve partial Differential equations", implements a numerical solution for the equations governing compressible and incompressible fluid flow in three dimensions. The code is based on the spectral element method (SEM) and is designed to be used for scale-resolving simulations 
(LES and DNS). It is written in Fortran, and uses MPI and OpenACC to provide parallelism at both coarse and fine-grained levels, and is accelerated to be able to use the newest GPU architectures. The code has been entirely developed within the Barcelona Supercomputing Center (BSC) and is available open-source through its git repository.

The seminar will showcase how high-order continuous Galerkin methods can be used for solving complex fluid dynamics problems, focusing on stabilisation through entropy viscosity. Participants will learn how this approach ensures numerical stability and accuracy in simulations of turbulent flows and some of the strategies used for efficient parallelization of the code.

Speaker: Prof. Arnau Miró 
Tenure-track professor at UPC Universitat Politècnica de Catalunya with experience in high-fidelity computational fluid dynamics. He has specialized in HPC, machine learning, and reduced-order modeling for aerospace and environmental applications.
