Journal of Mathematics, Volume 2025, Issue 1, 2025.We aim to introduce a numerical method to solve a system of two‐dimensional nonlinear integral equations of Volterra–Fredholm type with the second kind on nonrectangular domains. The method estimates the solutions of the system by a discrete collocation method based on radial basis functions constructed on scattered points.

Remeshing in the finite cell method for different types of geometry descriptions
Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 4, December 2024.Abstract The numerical structural analysis of problems with complex geometries can be challenging, especially if standard finite elements are used. In contrast, immersed methods, such as the finite cell method, relieve the mesh generation such that simply shaped elements/cells can be used.

A shape optimization pipeline for marine propellers by means of reduced order modeling techniques
International Journal for Numerical Methods in Engineering, Volume 125, Issue 7, 15 April 2024.Abstract In this article, we propose a shape optimization pipeline for propeller blades, applied to naval applications. The geometrical features of a blade are exploited to parametrize it, allowing to obtain deformed blades by perturbating their parameters. The optimization is performed using a genetic algorithm that exploits the computational speed‐up

Anisotropic Radial Basis Function Methods for Continental Size Ice Sheet Simulations
, 2017 In this paper we develop and implement anisotropic radial basis function methods for simulating the dynamics of ice sheets and glaciers. We test the methods on two problems: the well-known benchmark ISMIP-HOM B that corresponds to a glacier size ice and ...

Polyharmonic Multiquadric Particular Solutions for Reissner/Mindlin Plate [PDF]
Mathematical Problems in Engineering, 2015 Analytical particular solutions of the polyharmonic multiquadrics are derived for both the Reissner and Mindlin thick-plate models in a unified formulation. In the derivation, the three coupled second-order partial differential equations are converted into a product operator of biharmonic and Helmholtz operators using the Hörmander operator ...

Water Resources Research, Volume 60, Issue 3, March 2024.Abstract The ICESat‐2 and GEDI missions were launched in 2018, becoming the new generation of space‐borne laser altimeters. These missions provide unprecedented global geodetic elevations, opening great opportunities for water level monitoring. The potential of these altimeters has been demonstrated in open‐water environments such as lakes, rivers, and
