1.	The staggered grid needs no interpolation to get the __________(a) velocity field in the momentum equation(b) velocity field in the continuity equation(c) kinetic energy field in the momentum equation(d) kinetic energy in the continuity equationThis question was addressed to me in exam.This is a very interesting question from Incompressible Flows in portion Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
Answer» Correct answer is (b) velocity field in the continuity equation The best I can explain: In the STAGGERED grid formation, as the PRESSURE is already stored in a different place from the pressure, there is no need of any INTERPOLATION to FIND the velocity field required for the continuity equation.
