- can help when designing/debugging blockMesh layouts - propagate low-level cellModel methods face() and edge() to cellShape STYLE: relocate blockMesh OBJ output to application only - remove blockTopology files in cleanCase function - improve code consistency in top-level blockMesh, PDRblockMesh generation.

Description
|
|
Utility to clean surfaces.
|
|
|
|
Current functionality
|
|
- removes baffles
|
|
- collapses small edges, removing triangles.
|
|
- converts sliver triangles into split edges by projecting point onto
|
|
base of triangle.
