In CFD, the computational domain must represent the physical domain correctly so that the results will reflect the true nature of the real case. Consider a fluid problem "Water flowing through a two-dimensional tube bend” with a diameter of 1 m and 5 m total length. The distance from the inlet to the 90° bend location is 2.5 m. 1. Develop (create) a 2-D computational domain 2. Generate different structured meshes for the computational domain you created in "1". check the quality of the meshes using the mesh metrics such as orthogonal quality, skewness, and aspect ratio, and provide your final remark. Mesh size Orthogonal Skewness (max) Aspect ratio Remark quality (min) (max) Propose one mesh you choose for the simulation and state why you choose it. 3.

Provide appropriate boundary names for the domain.
