1.	Which of these arrangements of the velocity and pressure gradient components is suitable for non-orthogonal grids?(a) Staggered arrangement with covariant base(b) Collocated arrangement(c) Staggered arrangement(d) Covariant arrangementThe question was asked by my college director while I was bunking the class.I would like to ask this question from Numerical Methods topic in division Numerical Methods of Computational Fluid Dynamics
Answer» Correct choice is (b) COLLOCATED arrangement Easy EXPLANATION: The collocated arrangement is the SIMPLEST as all the variables share the same control volume. But this requires more INTERPOLATION. When the grid is non-orthogonal, the collocated arrangement is the best as the other ARRANGEMENTS are more difficult.
