An adaptive meshless method of line based on radial basis functions [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2015 In this paper, an adaptive meshless method of line is applied to distribute the nodes in the spatial domain. In many cases in meshless methods, it is also necessary for the chosen nodes to have certain smoothness properties.

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 81-95, March 2026.In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

A Localized Meshless Technique for Generating 3-D Wind Fields
Computation, 2018 A localized meshless method is used to simulate 3-D atmospheric wind fields for wind energy assessment and emergency response. The meshless (or mesh-free) method with radial basis functions (RBFs) alleviates the need to create a mesh required by finite ...

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Real‐time meshless deformation [PDF]
Computer Animation and Virtual Worlds, 2005 AbstractIn this paper, we articulate a meshless computational paradigm for the effective modeling, accurate physical simulation, and real‐time animation of point‐sampled solid objects. Both the interior and the boundary geometry of our volumetric object representation only consist of points, further extending the powerful and popular method of point ...
