You are all invited to this week's NOMADS seminar at GSSI.
The seminar will be given on Wednesday December 16 at 17:00
(CET) by Alexander Viguerie from GSSI.
Title, abstract and zoom link are below.
This is the last seminar of 2020 and we will then be back on Jan 13,
2021.

Title:
Efficient, stable, and reliable solvers for the Steady
Incompressible Navier-Stokes equations: application to Computational
Hemodynamics.
Abstract:
Over the past several years, computational fluid dynamics (CFD)
simulations have become increasingly popular as a clinical tool for
cardiologists at the patient-specific level. The use of CFD in this
area poses several challenges. The clinical setting places heavy
restrictions on both computational time and power. Simulation
results are usually desired within minutes and are usually run on
standard computers. For these reasons, steady-state Navier-Stokes
simulations are usually preferred, as they can be completed in a
fraction of the time required to run an unsteady computation.
However, in many respects the steady problem is more difficult than
the unsteady one, particularly in regards to solving the associated
linear and nonlinear systems. Additionally, boundary data for
patient-specific problems is often missing, incomplete, or
unreliable. This makes the determination of a useful model
challenging, as it requires the generation of reliable boundary data
without introducing heavy computational costs. This seminar will
address these challenges, as well as some others, and introduce new
techniques for workarounds. Results from patient-specific cases will
be presented and discussed.
