The National Competence Centers in HPC of the Czech Republic and Turkey are inviting you to the jointly developed tutorial High Performance CFD using OpenFOAM.
The tutorial provides an introduction to the widely used OpenFOAM open source package for CFD simulations on HPC infrastructure. Problem solving methods for both the implementation of user boundary conditions into OpenFOAM and turbulence models will be presented in detail.
Introduction & Running OpenFOAM in parallel on HPC infrastructure
We will make an introduction to the basics of OpenFOAM solvers. We will explain fundamental numerical aspects of OpenFoam solver and present OpenFOAM solvers for different applications with some demonstrations.
OpenFOAM - The basics for fast and accurate solutions
The lecture shows the possibility of converting data from commercial ANSYS Fluent code to OpenFOAM environment, setting initial and boundary conditions on standard benchmark - Mixing elbow. Comparison of the solution on three types of meshes, (tetrahedra, tetrahedral with inflation, polyhedral) and implementation of the boundary conditions using codeStream will also be part of the talk.
Introduction to turbulence models
The lecture is focused on the elementary theory of fluid flow and the mathematical model of fluid flow. The fundamental set of differential equations describing fluid flow is outlined, and problems of turbulent flow are introduced. Next, the existing possibilities of turbulent flow modelling are discussed. The problem of validation and verification of numerical simulation of flow is outlined at the end.
