Orthogonal Grid Generation

In this chapter, a brief introduction of algebraic grid generation, transfinite interpolation and elliptic grid generation is given. In particular, a two-step elliptic grid generation method developed by Spekreijse [121] is introduced, which can generate high quality and orthogonal grids near the boundary. The smooth and orthogonal grid for the LES case of MVG and Ramp is generated by the above method.

Keywords: Algebraic grid generation, Elliptic grid generation, Orthogonal grid generation, Transfinite interpolation.
