List of Minisymposia
Each Minisymposium is expected to consist of at least one 2-hour session (6 presentations of 20 minutes
each). The number of sessions of each MS will be determined by the multiples of six papers submitted.
In each MS a Keynote lecture is allowed every two full sessions of the MS, where a keynote presentation normally comprises two presentation slots. This means you should have at least 10 confirmed presentations to schedule a KL.
The above scheduling includes time for questions and discussion.

Machine learning (ML) and quantum computing have each begun to reshape computational fluid dynamics (CFD), promising speed-ups that could open up new application regimes. Yet using ML to tackle “big science” questions that are qualitatively out of reach for traditional simulation—such as uncovering underlying physical laws from limited observations—is still early-stage. Progress in quantum computing for CFD has arguably lagged further, because current hardware limitations have constrained large-scale numerical experimentation, keeping many capability assessments more theoretical and first-principled.
This workshop aims to bring together contributions and discussion on how ML and quantum methods might jointly address these frontier scientific questions, while also showcasing recent advances from each field individually. Tentative themes include:
1) Turbulence closures as inverse problems: addressing non-uniqueness, hidden variables, and multi-regime physics under sparse or biased data. Bayesian/probabilistic closures with physical constraints are a baseline, potentially complemented by quantum-enhanced sampling to explore complex posteriors.
2) Scientific inference for PDEs beyond physics-informed approaches: shifting focus from accelerating known models to inferring the governing physics in unknown regimes, including unknown forcings, constitutive laws, and boundary/initial conditions. Hybrid quantum–classical variational inference for PDE-constrained problems and physics-informed methods provide starting points, with open questions on what comes next.
3) Rare events in fluids (tails, transitions, extremes): using quantum-ML to predict and characterize low-probability but high-impact phenomena (e.g., laminar–turbulent transition, blow-up events, rogue-wave analogs, intermittency) that are poorly sampled in simulations yet can dominate real-world risk and undermine numerical reliability.
4) Multi-physics CFD as a grand inverse problem: treating condensation, phase change, reactive flows, and phase-transition kinetics as inference problems where governing physics is uncertain and validation data is indirect. Key directions include constrained constitutive modeling, posterior exploration in stiff kinetics/phase change, multi-fidelity/multi-scale data assimilation, and regime classification from sparse samples.

This minisymposium focuses on the development and application of Reduced Order Models (ROMs) for complex environmental systems, with particular emphasis on oceanic and atmospheric processes (e.g., circulation, waves, and wave-structure interactions). ROMs offer efficient alternatives to high-fidelity simulations by simplifying large-scale models while preserving critical system dynamics, making them highly valuable for real-time prediction and analysis.
Oceanic and atmospheric flows have significant societal impacts, but due to the massive physical scales involved, they pose severe computational challenges for operational forecasting. Machine learning and data-driven models—applying techniques such as dynamic mode decomposition (DMD) and its variants, physics-informed neural networks (PINNs), and generative AI approaches—are proving able to bridge this gap.
The minisymposium invites researchers and practitioners from diverse computational fields to discuss advancements in creating these reduced-order frameworks. Participants are encouraged to contribute to the ongoing dialogue on the advantages, limitations, and future directions of using hybrid or purely data-driven approaches to model complex physical processes that traditionally require prohibitive computational resources.

This minisymposium comprises the study of protective structures to mitigate natural hazards caused by environmental flows. These structures include, but are not limited to:
- Breakwaters, seawalls, groynes, etc. for coastal protection against tides, currents, water waves, and storm surges.
- Retaining walls, gabion meshes, and drainage systems to control erosion and prevent landslides and floods.
- Artificial windbreaks to protect soil from erosion and to keep snow from drifting.
The main focus of the minisymposium is on the design of relevant structural components, the simulation of complex fluid flows around or within the components, and the evaluation of the efficacy and the feasibility of the protective measures. Topics range from the reinforcement of existing structures to prevent floods and collapses, the dissipation and the redirection of flows using engineered obstacles and channels, e.g., by modifying their shape, up to procedures that
minimize the risk and the potential damage of catastrophic natural disasters, such as tsunami, earthquakes, and hurricanes.
Advances and novel approaches to obstacle flow problems in computational fluid mechanics, investigations of phenomena at complex interfaces between fluids and solid structures, as well as contributions to the mathematical modeling, treatment, and numerical simulation of physical processes that may lead to hazardous events are within the scope of this minisymposium.

Fluid–poroelastic structure interaction problems arise in many biomedical and engineering applications, including deformable porous materials, tissue perfusion, implantable bioartificial devices, and drug-eluting stent design [1, 2]. In this talk,we present a fully discrete second-order explicit Robin-Robin splitting scheme for the time-dependent Stokes–Biot problem on fixed domains. The method is based on a Robin reformulation of the fluid–poroelastic interface conditions and combines BDF2 time discretization in the Stokes and Biot subproblems with AB2 extrapolation of the interface data. This produces a fully explicit partitioned algorithm in which the fluid and poroelastic subproblems can be solved independently and in parallel at
each time step [4].
We also establish a discrete stability estimate for the fully discrete scheme using BDF2 energy identities, a decomposition of the extrapolated interface terms, and trace inequalities. The resulting stability bound is closed under a parabolic CFL condition linking the time step and mesh size. Besides, we develop an a priori error analysis in a discrete energy framework using a Fortin projection for the fluid variables and Ritz-type projections for the poroelastic variables. Under suitable regularity assumptions and second-order accurate initialization, we prove convergence in the natural energy norms, with total errors in fluid velocity, structure velocity, pore pressure, and elastic displacement bounded by 𝐶(ℎ𝑘 + Δ𝑡2). Numerical experiments based on manufactured solutions confirm the predicted convergence. This work extends earlier explicit splitting analysis for fluid–poroelastic interaction [3] and provides a justified,
second-order, parallelizable method for Stokes–Biot problem.

Immersed Boundary Methods (IBM) have been attracting strongly increased attention during the past decades. Their central principle is to extend a domain of computation to a larger one, typically with a simple shape, which is easy to mesh. On this extended domain a finite element type computation is performed, distinguishing between regions interior and exterior to the original domain. Under the denotation ‘fictitious domain’ or ‘embedded domain methods’ the central principle has been followed already since the 1960ies. The recent new interest results from innovative and efficient algorithmic developments, from mathematical analysis showing optimal convergence despite the presence of cut elements, the possibility to efficiently link these methods to various types of geometric models and from many new engineering applications. Many variational versions of Immersed Boundary Methods have been developed, like CutFEM, the Finite Cell Method, Unfitted Finite Elements (in the traditional and hybridizable form), the Shifted Boundary Method, Phi-FEM, Immersogeometric Analysis, just to name a few.
This mini-symposium will focus on Immersed Boundary Methods of variational type, and the various aspects that make them successful in addressing complex problems, namely: mathematical analysis, a priori and a posteriori error estimation and adaptivity, advanced numerical integration procedures, data structures and parallel scaling of algorithms, integration with CAD models and non-standard geometric representations, and applications. The scope of this mini-symposium is to be as broad as possible in terms of applications, such as, but not limited to: CFD of compressible and incompressible flows, fluid/structure interaction, and any other types of domain coupling. Topics will also include computational homogenization techniques and the connection between Immersed Boundary Methods and meta-algorithms, such as the ones used in Uncertainty Quantification, Reduced Order Models, Machine Learning and Artificial Intelligence, Direct and Inverse Problems, and Topology Optimization.
