is there a way to vary packing height in ansys and does this effect darcy number. my point is if permeability is fixed how we can very darcy number. or simply how we can vary darcy number in ansys

Effect of packing height and location of porous media on heat transfer in a cubical cavity
Are extended Darcy simulations sufficient?”

i am attaching a paper clip in which they kept permeability constant but vary the darcy number by varying the packing height  please help me understand
