Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Volcanic calderas are large depressions formed by the rapid collapse of overlying rock into a magma chamber during eruptions. We utilize Smoothed Particle Hydrodynamics (SPH), a continuum, meshfree numerical method, to study the 2018 caldera collapse at Kīlauea volcano in Hawaii.

Local continuum consistent peridynamics with bond‐associated modeling and dynamic fracture
GAMM-Mitteilungen, Volume 49, Issue 1-2, March/June 2026.Abstract This paper explores the theoretical foundations and practical challenges of peridynamics as a nonlocal continuum mechanics method. We establish connections between classical continuum mechanics principles and peridynamics formulations, with a particular focus on understanding how the pairwise force function in peridynamics relates to stress ...

Meshfree Variational-Physics-Informed Neural Networks (MF-VPINN): An Adaptive Training Strategy
AlgorithmsIn this paper, we introduce a Meshfree Variational-Physics-Informed Neural Network. It is a Variational-Physics-Informed Neural Network that does not require the generation of the triangulation of the entire domain and that can be trained with an ...

Algebraic-volume meshfree method for application in finite volume solver [PDF]
, 2019 Nowadays the finite volume (FV) method remains the most popular choice for Computational Fluid Dynamics (CFD). But few meshfree methods have been developed based on the framework of existing FV codes which can boost the development of the meshfree method.

Numerical Analysis of a Benjamin–Bona–Mahony Type Equation in a Noncylindrical Domain
Mathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 818-834, 30 January 2026.ABSTRACT Numerical analysis and simulation for the approximate solution of a Benjamin–Bona–Mahony type equation defined in a noncylindrical domain are presented in this article. The approximate problem is defined using the linearized Crank–Nicolson Galerkin method, which results in a linear algebraic system at each time step while maintaining quadratic
