singleCellMesh
|
|
|
|
Description
|
|
Reads all fields and maps them to a mesh with all internal faces removed
|
|
(singleCellFvMesh) which gets written to region "singleCell".
|
|
|
|
Used to generate mesh and fields that can be used for boundary-only data.
|
|
Might easily result in illegal mesh though so only look at boundaries
|
|
in paraview.
