Create a layer of cell above ground of 1m tall
 

Dear Sir/Madam,

I am using Gambit to form the mesh. I would like to simulate the effect of flow at pedestrian level (about 2m above ground) in a 3D model, therefore, I need to create 2 fine layers of cell (each of height 1m) above the ground of area of interest. I don't know how to do this. I have tried the "Mesh=>Boundary Layer" in Gambit, but it only create the fine mesh on the faces of buildings, it is not for a whole layer of cells above ground. Would anyone please help me....

Regards, Sammi
