2.5.1. Defining the Geometry

Try these first

1. 1.

   What does CFD stand for?

   Hint

   Think about what aspects of fluid dynamics benefit from computation.

2. 2.

   What is the purpose of defining geometry in CFD?

   Hint

   Consider how a model would be used before running simulations.

3. 3.

   What does CFD stand for?

   • Computational Fluid Dynamics
   • Computerized Flow Designs
   • Cyclic Flow Dynamics

   Hint

   Look for the focus on 'Computational' and 'Fluid'.

4. 4.

   True or False: The geometry must be defined before discretizing the domain.

   • True
   • False

   Hint

   Consider what comes first: the model or the breakdown?

5. 5.

   Consider a scenario where a certain predefined geometry leads to unnecessary complexity in the CFD simulation. How would you redesign the geometry to optimize simulation efficiency?

   Hint

   What aspects of the design contribute to excess calculations?

6. 6.

   Explore a numerical simulation error resulting from poor mesh quality in a CFD model. Describe steps to correct the mesh generation.

   Hint

   How does the resolution of mesh impact solution accuracy?
