Twenty configurations are each analysed in \( 90 \) seconds. The full sweep takes

  • A.20 minutes
  • B.30 minutes
  • C.3 minutes
  • D.5 hours

Answer: B

Correct answer: 30 minutes

The total is

\[ 20 \times 90 = 1800 \text{ s} = 30 \text{ minutes} \]

Half an hour for a two-variable sweep is workable; the same arithmetic with three variables and eighty cases would take two hours, and with four it becomes an overnight run. This is exactly why conceptual design uses low-fidelity, fast methods and leaves computational fluid dynamics and finite element analysis to later phases.
