Which of these is an advantage of the SIMPLEC algorithm over the SIMPL

1.	Which of these is an advantage of the SIMPLEC algorithm over the SIMPLE algorithm?(a) No over-relaxation(b) No under-relaxation(c) No undershoots(d) No extra termsThe question was asked during an interview.My query is from Incompressible Flows topic in portion Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
Answer» Correct choice is (B) No under-relaxation To explain: In the SIMPLE algorithm, the whole momentum equation is used. So, for the CORRECTION of PRESSURE and velocity, an under-relaxation factor is used. But, as the SIMPLEC algorithm omits all the insignificant TERMS in the momentum equation, this under-relaxation becomes unnecessary.
