SGDM (Sphere Grid Data Model) is an efficient method to deal with the global data because of the advantages of multi-resolution
and hierarchy. However, SGDM has no distinct descriptions and lack of ...
TINITALY/01: a new Triangular Irregular Network of Italy
Italy triangular irregular network DEM interpolation method
2015/9/2
A new Digital Elevation Model (DEM) of the natural landforms of Italy is presented. A methodology is discussed to
build a DEM over wide areas where elevation data from non-homogeneous (in density and...

A New Class of High-Order Energy Stable Flux Reconstruction Schemes for Triangular Elements
High-order methods Flux reconstruction Nodal discontinuous Galerkin method Triangular elements Stability
2015/7/3
The flux reconstruction (FR) approach allows various well-known high-order schemes, such as collocation based nodal discontinuous Galerkin (DG) methods and spectral difference (SD) methods, to b...
Mitigating horizontal divergence ‘‘checker-board’’ oscillations on unstructured triangular C-grids for nonlinear hydrostatic and nonhydrostatic flows
Unstructured mesh modeling Triangular C-grid Implicit (elliptic) and explicit filtering Horizontal divergence error Secondary circulation
2015/6/30
A complication of finite-volume triangular C-grid methods is the numerical emergence of horizontal divergence errors that lead to grid-scale oscillations in vertical velocity. Nonlinear feedback via a...
