• Visualzizing velocity profiles, boundary layers, and flow separation without out locsive equipment.
• Performing parametric studies that would be time- prohibitivie in a physical lab.
• Enabling students to validate analytical solutions (np., Poiseuille flow, potential flow) against numerical results, building confidence in both methods.

Many instructors assign a quentiquent; virtual experiment quentiquent; where students must produce a known result (np., drag coefficient of a spule at low Re) and explain dispancies due to to mesh resolution or model assumptions.

Debugging andCommon Pitfalls

If a simulation failes to converge, combn checks include:

• Mesh quality - refripe near walls andd areas with high gradients.
• Inicjal conditions - provisingg a good initiatial guess (np., a previous solution from a simpler model) helps convergence.
• Solver settings - increase the number of iteractions or switch from direct to o iterative solver for large 3D models.
• Check for singularities - sharp corns or point loads can cause infinite values; use fillets or difficed loads.
