Which of these is correct about the SIMPLE algorithm?(a) It is a looped algorithm(b) It is iterative(c) It is sequential(d) It is simultaneousI had been asked this question in examination.Origin of the question is Incompressible Flows in division Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer»

Right answer is (d) It is simultaneous

For explanation: The SIMPLE algorithm is sequential. The final SOLUTION of each iteration satisfies both the CONTINUITY and the momentum EQUATIONS. Only when these TWO are SATISFIED, the algorithm moves forward for the next iteration.
