1.	In FVM methods, cut-off width depends on ____________(a) the PDE(b) the algebraic equation(c) the grid-size(d) the discretization methodI have been asked this question in my homework.My question is taken from Large Eddy Simulation for Turbulent Models in section Turbulence Modelling of Computational Fluid Dynamics
Answer» CORRECT choice is (c) the grid-SIZE The best I can EXPLAIN: When we use the finite volume method, it is pointless to use a cut-off width which is smaller than the grid size. If such cut-off width is chosen, the accuracy of the method in capturing the EDDIES will be AFFECTED.
