On the Solution of Boundary Value Problems Set in Domains With Moving Boundaries

Mathematical Methods in the Applied Sciences, Volume 48, Issue 10, Page 10427-10441, 15 July 2025.
ABSTRACT We construct solutions for time‐dependent boundary value problems set in moving domains with Dirichlet, Neumann, and mixed boundary conditions. When the boundaries are time deformations of an initial boundary along a vector field, we can refer the boundary problem to a fixed domain at the cost of increasing the complexity of the coefficients ...

SDF‐Guided Point Cloud Generation Framework for Mesh‐Free CFD

International Journal for Numerical Methods in Fluids, Volume 97, Issue 7, Page 1035-1056, July 2025.
This paper presents different methods for generating clouds of points around objects for use with meshless methods in computational fluid dynamics. This image shows the cloud generated around the original ROBIN body. ABSTRACT Meshing is a bottleneck of CFD workflows, especially when complex geometries are considered.

Eigenvalue Approach to Dense Clusters in Hypergraphs

Journal of Graph Theory, Volume 109, Issue 3, Page 353-365, July 2025.
ABSTRACT In this article, we investigate the problem of finding in a given weighted hypergraph a subhypergraph with the maximum possible density. Using the notion of a support matrix we prove that the density of an optimal subhypergraph is equal to ∥ A T A ∥ for an optimal support matrix A. Alternatively, the maximum density of a subhypergraph is equal

Structure‐Preserving Approximations of the Serre‐Green‐Naghdi Equations in Standard and Hyperbolic Form

Numerical Methods for Partial Differential Equations, Volume 41, Issue 4, July 2025.
ABSTRACT We develop structure‐preserving numerical methods for the Serre–Green–Naghdi equations, a model for weakly dispersive free‐surface waves. We consider both the classical form, requiring the inversion of a nonlinear elliptic operator, and a hyperbolic approximation of the equations, allowing fully explicit time stepping.
