Mesh Zone
 

Hello,

I'm newbie on FLUENT and I would like to know how to realize a different mesh on one body: it is a paved 200x200x100m and at center the size shall be 0.4 m for a hemisphere of radius R=10m and 1m up for R = 22m and approximately 2 to 4m on the rest of the structure.

Can you help me? please ^ ^
