[R_21]

Hi,
I have been trying to create a geometry for my flat plate simulation required for my problem. I am new to blockMesh (previously was using gmsh and couldn't use for the current case.)
I am attaching my blockmesh dict. I dont understand how to apply the grading in the mesh. Also, tried using the calculator for grading by setting the mesh cell size as 0.05 and applying the number of cells for each block.
