Introduction to Multiphysics

Introduction to Multiphysics

Complex Pressure-Related Flow Phenomena in CFD

This course presents Dr. József Nagy's comprehensive introduction to Multiphysics simulations. The course's structure is divided into three sections focusing first on individual simulation components, and then on conjugate heat transfer and fluid-structure interaction. The course emphases both theoretical and practical aspects. The course aims to provide with an understanding of the individual domains and their coupling, including best practices and common pitfalls. It is designed for learners to be progressed linearly or to delve into specific topics as needed. The course content is software-agnostic and is centered around principles that can be applied across different software suites.

József Nagy

Dr. József Nagy graduated from the Vienna University of Technology in Physics and finished his PhD in Chemical Engineering. For six years he held the position of a post-doc at the Johannes Kepler University, where he worked on polymer materials. He is the Chair of the Technical Committee for Tutorials and Documentation in the OpenFOAM Governance System and is Chief-Editor at the OpenFOAM Journal. He has the biggest YouTube channel with specialized tutorials for learning Computational Fluid Dynamics (CFD) with OpenFOAM. Currently he is a CFD engineer at eulerian-solutions. His areas of interest are diverse, multiphase flows, complex materials, porous media, fire and species dispersion, Fluid-Solid Interaction (FSI) and model development and implementation as well as custom workflows for specific applications.
