A simple, effective and high-precision boundary meshfree method for solving 2D anisotropic heat conduction problems with complex boundaries [PDF]
Scientific ReportsA simple, effective and high-precision boundary meshfree method called virtual boundary meshfree Galerkin method (VBMGM) is used to tackle 2D anisotropic heat conduction problems with complex boundaries. Temperature and heat flux are expressed by virtual

A meshfree method for simulating myocardial electrical activity. [PDF]
Comput Math Methods Med, 2012 An element-free Galerkin method (EFGM) is proposed to simulate the propagation of myocardial electrical activation without explicit mesh constraints using a monodomain model. In our framework the geometry of myocardium is first defined by a meshfree particle representation that is, a sufficient number of sample nodes without explicit connectivities are

Cardiac Electrophysiology Meshfree Modeling through the Mixed Collocation Method
Applied Sciences, 2023 We present the meshfree mixed collocation method (MCM) for cardiac electrophysiology simulation. Capitalizing on the meshfree property of MCM, we introduce an immersed grid approach for automated generation of meshfree node grids from medical image data.

Meshfree particle method [PDF]
Proceedings Ninth IEEE International Conference on Computer Vision, 2003 Many of the computer vision algorithms have been posed in various forms of differential equations, derived from minimization of specific energy functionals, and the finite element representation and computation have become the de facto numerical strategies for solving these problems. However, for cases where domain mappings between numerical iterations

A meshfree Lagrangian method for flow on manifolds [PDF]
International Journal for Numerical Methods in Fluids, 2021 AbstractIn this article, we present a novel meshfree framework for fluid flow simulations on arbitrarily curved surfaces. First, we introduce a new meshfree Lagrangian framework to model flow on surfaces. Meshfree points or particles, which are used to discretize the domain, move in a Lagrangian sense along the given surface.
