Angle Deficit Approximation of Gaussian Curvature and Its Convergence over Quadrilateral meshes
Gaussian Curvature Quadrilateral Mesh Convergence

2012/8/7
We propose a discrete approximation of the Gaussian curvature over quadrilateral
meshes using a linear combination of two angle de痗its. Suppose a surface mesh is
obtained from a sampling of a smooth...
Convergence of a Force-Based Hybrid Method in Three Dimension
Convergence a Force-Based Hybrid Method Three Dimension
font style='font-size:12px;'>
2012/8/7
We study a force-based hybrid method that couples atomistic model with Cauchy-Born elasticity model. We show the proposed scheme converges to the solution of the atomistic model with second order accu...
