Description

For blocks with overset data only, the donor edge length ratio is calculated as the ratio between the donor cell edge lengths and the local edge lengths of the receiving fringe point's cells.

 

Tip: Overset gridding refers to the use of multiple disconnected grids to discretize the flow domain. The component grids, which can be any size, type, or shape, need only overlap each other to completely cover the solution domain.
