Azita Soleymani Guest Posts: n/a	I am looking for an expression to demonstrate the relation between the numerical(false) diffusion and Cell peclet number in QUICK scheme. What is the acceptable range of cell Peclet number in solving the convection-diffusion problem where the convection term is as important as the diffusion term. Thanks in advance for your help. Azita
