Location: Germany
Web Page: http://www.ovgu.de/isut/LSS/CFD/CFD_Challenge.html
Contact Email: janiga@ovgu.de

Type of Event: Other, International
 
Description:

In the recent years various simulation challenges have been
organized in order 
to check the applicability of the computational hemodynamics
for intracranial 
aneurysms. Radaelli et al. [1] performed a comparison for
virtually stented 
patient-specific cases using flow diverters. Steinman et al.
[2] compared the 
velocity and pressure values obtained by various groups in a
giant aneurysm. 
One of the main difficulties when performing computational
fluid dynamics 
(CFD) for patient-specific cases is the prediction of the
rupture probability. 
The current challenge involves two patient-specific
MCA-aneurysms that should 
be analyzed by CFD in a blind test. One of the provided data
sets corresponds 
to a ruptured aneurysm, while the other one can be
considered as unruptured. 
The ruptured case is documented with intra-operative video
recording. 
Therefore, the exact ruptured site of the aneurysm is known.

-The reconstructed surface geometries will be provided after
sending an e-mail 
to janiga_at_ovgu.de
-The participants are free to choose their computational
model, software, 
boundary condition etc.
-The participants are also free to use any criteria to
analyze the obtained 
solutions with a view to rupture prediction. It is expected
that the participants 
should predict: 1) which one was the ruptured aneurysm based
on their 
computational results; 2) at which location the rupture took
place.
