چکیده

In this paper a non-traditional approach to generation of orthogonal/Cartesian grids with local refinement tetra-hedrons near STL boundary on the basis of up-to-date CAD systems is considered. The features of the algorithm of constructing orthogonal grids are explained. Examples of constructed grids are presented.

Automatic Adaptive Meshing for Efficient Electrostatic Boundary Element Simulations

The bounda y element method (BEM) is well suited for the electrostatic analysis of large, geometrically complex structures. When highly accurate solutions are required, the discretization (meshing) of the geometry becomes increasingly important. A scheme is required to construct optimal meshes, in the sense that maximum accuracy of the solution can be achieved with minimal computational eflort....

An immersed boundary method for compressible flows using local grid refinement

This paper combines a state-of-the-art method for solving the three-dimensional preconditioned Navier–Stokes equations for compressible flows with an immersed boundary approach, to provide a Cartesian-grid method for computing complex flows over a wide range of the Mach number. Moreover, a flexible local grid refinement technique is employed to achieve high resolution near the immersed body and...
