Meshing for simulations in ANSYS FLUENT -- 2

Job ID: 33737160

Budget: ₹1,500 – ₹12,500 INR

I want to mesh a square cylinder enclosed in a rectangular domain. Dimensions are:
side of square cylinder: 1 m
upstream distance: 20 m
downstream distance: 40 m
height of domain 60 m

I am enclosing a sample 2D mesh. The project is to create a 3D mesh so that I could do numerical simulations on it with dynamic meshing. Dynamic meshing setting will be done in the circular zone near the square cylinder.
