Talk:Structured Grids

From View

It's mentioned that "The updates are logically concurrent, but in practice are implemented as a sequential sweep through the computational domain. Updates may be in place, overwriting the previous version, or use two versions of the grid." However, the updates are NOT logically concurrent in something like Gauss-Seidel. Does that mean Gauss-Seidel is not to be considered as a structured grid operation?
