A Numerical Simulation of Anomalous Electro-Diffusion of Ions in Spiny Dendrites Using a Local Petrov-Galerkin Method

پژوهش‌های ریاضی, 2021
The cable equation is one the most fundamental mathematical models in the neuroscience, which describes the electro-diffusion of ions in denderits. New findings indicate that the standard cable equation is inadequate for describing the process of electro-

Adjoint-based shape optimization of fin geometry for heat transfer enhancement in solidification problem

Journal of Thermal Science and Technology, 2016
In the present study, an adjoint-based shape-optimization method is formulated for heat transfer enhancement in liquid-solid phase change problems, in which heat conduction is dominant.

Assessment of implicit adaptive mesh‐free CFD modelling

International Journal for Numerical Methods in Fluids, Volume 96, Issue 5, Page 670-700, May 2024.
The paper shows results from an implicit meshless method suitable for the analysis of external aerodynamic flows. This research is using a cloud of points instead of cells, and several stencils are compared for the discretization of the flow equations, along with a least‐squares method.

Meshless local Petrov-Galerkin method with complex variables for elasticity

Acta Physica Sinica, 2012
In this paper, the shape functions are obtained by the moving least-squares method with complex variable (MLSCV). The advantages of MLSCV are that the approximation function of a two-dimensional (2D) problem is formed with one-dimensional (1D) basis function, and the number of the undetermined coefficients is reduced, so it effectively improves the ...

Numerical Integration with Constraints for Meshless Local Petrov-Galerkin Methods

Computer Modeling in Engineering & Sciences, 2013
We propose numerical integration rules for meshless local Petrov- Galerkin methods (MLPG) employed to solve elliptic partial different equations (PDE) with Neumann boundary conditions. The integration rules are required to satisfy an integration constraint condition of Green’s formula type (GIC).
