Question

Which of these performance characters of the SIMPLEC algorithm match with the SIMPLE algorithm?

(a) Convergence per iteration

(b) Number of iterations

(c) Cost per iteration

(d) Total computational cost

The question was posed to me by my school teacher while I was bunking the class.

The doubt is from Incompressible Flows topic in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer 1

The correct answer is (c) Cost per iteration

Explanation: As the SIMPLEC algorithm is more converging than the SIMPLE algorithm, the SIMPLEC has more convergence per iteration, less number of iterations and hence less total computational cost than the SIMPLE algorithm. But, the computational cost per iteration is the same for both.
