A Study of the Partition of Unity-based T3-CNS and T3-DNS Finite Elements in Surface Fitting
Civil Engineering DimensionVarious alternative, enhanced finite element methods (FEMs) have been proposed to improve the accuracy and convergence of traditional FEM. One promising approach is the hybrid FEM-meshfree method using the partition of unity concept. This study examines

Meshfree Finite Differences for Vector Poisson and Pressure Poisson Equations with Electric Boundary Conditions [PDF]
, 2018 We demonstrate how meshfree finite difference methods can be applied to solve vector Poisson problems with electric boundary conditions. In these, the tangential velocity and the incompressibility of the vector field are prescribed at the boundary.

Meshfree volume-averaged nodal projection method for nearly-incompressible elasticity using meshfree and bubble basis functions [PDF]
, 2015 peer reviewedWe present a displacement-based Galerkin meshfree method for the analysis of nearly-incompressible linear elastic solids, where low-order simplicial tessellations (i.e., 3- node triangular or 4-node tetrahedral meshes) are used as a ...
