It can also be used for generating smooth orthogonal grids on complex multiblock domains. The following section guides the user through the steps required for using this code. The user is assumed to be familiar with basic grid generation and the numerical flow simulation process. Overview and Terminology PMAG is a structured grid adaptation algorithm.
Adaptation is done by redistribution of grid points.
The total number of grid points remains the same. There is no restriction on block - block connectivity. One block can be share its faces, edges or vertices with any number of blocks. The numbering of blocks is not important. Any block can be linked to any other block including itself.
