[Dottorcomp] Insalate di Matematica - B. Ghitti (Thursday 16/12)

[Mbs Insalate Di Matematica]

 As part of the series of seminars *"Insalate di Matematica"*, *Beatrice
Ghitti*, PhD student at the Università degli Studi di Trento, will deliver
a talk.
According to the current Covid regulations, the seminar will be held
in a *hybrid
mode* *(more information below)*.

Here the details:

*Date and time*: *16th December 2021, 2:00 pm (CET)*

*Title*:
*"Towards computationally efficient and accurate blood flow simulations in
the entire cardiovascular system"*

*Abstract*: In the last decades, mathematical modeling and simulation of
blood flow have become of primary importance in different contexts, from
basic research to clinical practice, employing different levels of model
complexity and sophistication, from lumped-parameter (0D) to distributed
(1D and 3D) models. A relevant contribution in this field is the global,
closed-loop, multiscale mathematical model of the entire human circulation
developed by M ̈uller and Toro (2014) and recently extended (2021).
Modeling blood flow in complex networks and cardiovascular models can
result in computationally expensive simulations, posing the need for
strategies and numerical methods to perform accurate and efficient
simulations. In this contribution, I will first present the Müller-Toro
global model and, in this framework, discuss the major challenges related
to the 1D blood flow modeling. After that, I will focus on one of the main
model components, the vascular (arterial and venous) networks, by
describing both the 1D and 0D nonlinear models for blood flow. I will
finally present a novel methodology we have developed to construct hybrid
1D-0D networks of vessels and to perform computationally efficient and
accurate blood flow simulations in such networks. This methodology is based
on high-order numerical coupling strategies and a-priori model selection
criteria which provide the best possible trade-off between accuracy of the
results and computational cost of the simulations.

*Information to attend in room 3014*
The seminar will take place in room 3014, at the building U5-Ratio,
Università degli Studi di Milano Bicocca. Unfortunately, only a limited
number of participants is allowed in presence, hence reservation is
mandatory. You can reserve at the following link:

We also remind that you will be required to exhibit your green pass at the
entrance of the building.

*Information to attend online*
The seminar will be streamed via Google Meet platform at the following

*** We inform you that the talk will be recorded and uploaded on our
website. If you join the talk after the starting time, we kindly ask you to
ensure that your microphone and webcam are turned off ***

You can find the poster of the event in the attachment. We are looking
forward to seeing you!
