Multi-Model Multi-Domain Computational Methods: Grids for Euler Computations

Below are examples of three-dimensional structured and unstructured grids that we use for steady Euler simulations of flow past an M6 wing. These pictures show close-up detail of the wing region, which is only a small fraction of the total computational domain. Although both grids pictured here are relatively coarse to enable reasonable visualization, we also use much finer discretizations in flow simulations (up to 2.8 million grid points) on various parallel machines.

Structured Grid Example

3D mapped structured grid based on a conforming hexahedral mesh. size: 98x18x18.

Unstructured Grid Example

3D unstructured grid based on a tetrahedralization of space. 2800 nodes.
