CASE I Lid-driven cavity flow
For this case the only moving wall is at the top. Some grids are used for this case. The shape is also changed.
The grid
Regular cell size for an initial approximation
Finest cells in the whole mesh
Regular cell size changing the shape of the box
Finest cells in the mesh at walls
Results
P obtained with the finest cells at walls
U for a regular cell size
U for a finest uniform grid
U for a regular size but changing the shape of the box
U for the finest cells at walls
