Which of these properties of the SIMPLE scheme matches with the energy

1.	Which of these properties of the SIMPLE scheme matches with the energy equation of the compressible flows?(a) Instability(b) Overshoots(c) Extra equation(d) Under-relaxation termI got this question during an interview.My question is taken from Compressible Flows in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
Answer» RIGHT option is (C) Extra equation Easiest explanation: Like the SIMPLE scheme, the energy equation of the compressible flows ALSO needs an under-relaxation term. The overall solution of the compressible flows follows the SIMPLE family of ALGORITHMS.
