I have created my mesh by blockMesh and I wanna know how can I determine the simpleGrading or expansion ratio for the prism layers. However, I am aware of that how can I calculate first layer thickness and number of them by some available tools. You know that thickness, number of devisions and length of the line are available, so is there any relation or formula for exp. ratio calculation?
