This required the addition of the meshToMesh class in the sampling library from OpenFOAM-2.2.x which is now named meshToMesh0.

Foam::mapNearestMethod
|
|
|
|
Description
|
|
Map nearest mesh-to-mesh interpolation class
|
|
|
|
Not volume conservative.
|
|
- cells outside other meshes bounding box do not get mapped
|
|
(initial filtering)
|
|
- all remaining cells will be mapped (with weight 1!)
|
|
- so take care when mapping meshes with different bounding boxes!
