3D Volume Calculation For the Marching Cubes Algorithm in Cartesian Coordinates
Shuqiang Wang
From a scalar field defined at the corner of a cube, an isosurface can be extracted using the Marching Cube algorithm. The isosurface separates the cell into two or more partial ce…
An Algorithm on Multivariate Interpolation for Cartesian Grid Complex Boundary Problems
Shuqiang Wang
We present a simple algorithm to select multivariate interpolation stencil with a Cartesian grid. We show its applicability by using this algorithm in the embedded boundary method…
A Comparison Study of Two Methods for Elliptic Boundary Value Problems
Jian Du, Shuqiang Wang, James Glimm +1
In this paper, we perform a comparison study of two methods (the embedded boundary method and several versions of the mixed finite element method) to solve an elliptic boundary val…
An Embedded Boundary Method for Two Phase Incompressible Flow
Shuqiang Wang, James Glimm, Roman Samulyak +2
We develop an embedded boundary method (EBM) to solve the two-phase incompressible flow with piecewise constant density. The front tracking method is used to track the interface. T…
