24 Class
25  Foam::mapNearestMethod
26 
27 Description
28  Map nearest mesh-to-mesh interpolation class
29 
30  Not volume conservative.
31  - cells outside other meshes bounding box do not get mapped
32  (initial filtering)
33  - all remaining cells will be mapped (with weight 1!)
34  - so take care when mapping meshes with different bounding boxes!
