This activity examines how boundary condition selection, domain extent, and discretization scheme affect both the accuracy and the stability of a CFD solution. A 90-degree pipe bend is simulated four times under systematically varied set-ups, and students record the resulting pressure drop and the number of iterations required for convergence in each case. One case is deliberately configured to produce a poor or divergent solution so that students practise diagnosing and correcting it rather than only reporting successful runs. The predicted minor loss coefficient of the bend is compared with published values.
