Welcome to SUN HYPE 2026!
During this event, our project leaders will guide small groups of early stage researchers in addressing challenging problems, proposed by them, that are of great relevance and interest to the research community. We hope that our participants will deepen their understanding of the state of the art, acquire new numerical techniques, actively contribute to the development of emerging research directions, and strengthen their professional connections within a solid and collaborative network.
Topics
Numerical Analysis, High-order numerical methods, Structure-preserving techniques, Exascale computing, Hyperbolic equations, Modeling and simulation, Mesh generation and optimization, Astrophysical applications ...

Projects and their leaders
Wasilij Barsukow
(CNRS, Université de Bordeaux, France)
Project:
New-generation Active Flux methods and their efficient implementation
We will develop new algorithms in the spirit of Roe's original Active Flux. The aim will be to simplify existing evolution operators and to extend this approach to new problems. Implementations will serve as a validation step, ensuring that the proposed methods run as intended and revealing any aspects that may require further refinement.
Availability: group complete, open waiting list.
Walter Boscheri
(CNRS, Université de Chambéry, France)
Project:
Exploiting moving meshes for involution preserving schemes
Keywords: plasma flows, unstructured meshes, divergence-free preservation, Arbitrary-Lagrangian-Eulerian.
Availability: group complete, open waiting list.
Giovanni Leidi
(Heidelberg Institute for Theoretical Studies, Germany)
Project:
Applying high-order structure-preserving finite volume methods to astrophysical applications
- There will be a shared core task:
implementing a higher-order (>=3) finite volume method suited for
modeling flows in stellar interiors.
- In addition, there will be more specialized tasks
(e.g. hydrodynamics, gravity, rotation, diffusive heat transport, boundary conditions and testing)
that can be tackled eventually separately by the team members, depending on their experience.
Availability: group complete, open waiting list.
Sandra May & Peter Munch
(Technische Universität Berlin, Berlin, Germany)
Project:
Hyperbolicity Meets Stochasticity
In this project, we will develop and implement numerical methods for solving stochastic hyperbolic conservation laws. To handle the stochastic components, advanced Monte Carlo techniques—such as multilevel Monte Carlo—will be employed. Participants are expected to have a background in numerical methods for hyperbolic problems, while only minimal prior knowledge of stochastic concepts is required (for example, familiarity with normal distributions and expected values). A central focus of the project will be investigating to what extent the discrete solutions of stochastic hyperbolic problems preserve key structural properties.
Availability: group complete, open waiting list.
Davide Torlo
(La Sapienza, Roma, Italia)
Project:
Equilibria preserving model order reduction methods for parametric problems
Keywords: Parametric problems, global flux methods, equilibria preserving, model order reduction, implicit methods, long time behavior, perturbations.
Availability: group complete, open waiting list.
Panagiotis Tsoutsanis - Takis
(Cranfield University, United Kingdom)
Project:
Exascale ready high-order methods
The focus will be on new formulation of existing methods so that they can perform on exascale hardware (CPUs+GPUs);
moreover, the project leader will make available some pre-exascale or exascale class systems to do test remotely.

How to arrive
By plane
The closest airport is the Airport of Chania,
which is about 20–25 minutes by car or bus from the city center of Chania.
On the island, there is another option: the international
Airport of Heraklion,
approximately 2–3 hours by car or bus from the city center of Chania.
Where to stay
There are plenty of options (hotel and apartments) on Booking.com and Airbnb.com,
so we recommend having a look and choosing what suits you best.
Below you can find a map of Chania's city center.
The most touristic area is highlighted by the red ellipse,
while the possible bus pick-up locations are marked with blue diamonds.

Where to go
(Work in progress – some links may be out of date - personal comments by Elena)
By walking:
- Nea Chora beach, just a normal city beach, 25 minutes walking
- Archeological museum of Chania, 15 minutes walking
By bus:
- Urban bus: link to bus schedule in greek ... otherwise use google maps
useful buses are 11 to Nea Chora beach (just a normal city beach), 21 to Xrisi Akti - Agioi Apostoloi (closest nice beaches)
- Intercity buses (see the highlighted pdf for buses info): you can go to
Loutraki and Marathi (very nice beaches!),
Seitan Limenes (very nice, like a swimming pool, but may be crowdy and you have to climb a bit),
Almerida (very nice, but further away than the others)
One day trip (for going by bus see the pdf):
- Lagoon of Balos (light-blue-green see, fantastic colors!!!): go by (big) boats from Kissamos port (reserve boat tickets at least the day before)
- Elafonissi (light-blue-green see, fantastic colors!!!, no bar on the beach)
- Falasarna (amazing sunset, very sunny, with beach bars)
- Paleochora (it is a less touristic village with long beaches with blue-deep see)
- Paralia Menies (Elena: "I have never been here, but I will try to go this time ... there should be boats going there departing from Agia Marina")
