The block course is supported and organized by Swiss Graduate School FOMICS - "Foundations in Mathematics and Informatics for Computer Simulations in Science and Engineering”, which is located at ICS.
The Institute of Computational Science (ICS) at the Università della Svizzera italiana announces a course designed for PhD and Master's students with knowledge of Functional Analysis on fluid dynamics and fluid-structure interaction analysis.
The course, starting on March 11th, 2020 is taught by Dr. Maria Giuseppina Chiara Nestola (ICS, ETH Zurich, CCMC) and will cover advanced mathematical and numerical aspects of Navier-Stokes equations and its coupling with solid-dynamics equations.
Please note that the course will continue after 20th April due to the suspension of in classroom teaching activities

Rationale
Fluid-structure Interaction is a complex phenomenon occurring in several fields including cardiovascular engineering,
geophysics, and turbomachinery.
This course aims to review three important ingredients of the fluid structure-interaction problem which are Navier-Stokes equations, Elastodynamics equations and their coupling.
The course will be split into two parts: the first one will focus on the theory and the numerical methods for Navier-Stokes equations, whereas the second part will focus on the theory and the numerical methods for the fluid-structure Interaction problem.
