A Detailed study on Snappy-Hex-Mesh in openFOAM - part 1
Objective: The Major Objective of this study is to use inbuilt meshing utility in OpenFOAM to Mesh a component and run a simulation without any other commerical meshing alogorithams. Backgroud: OpenFOAM is a Opensource CFD Library that is very popular, but it lacks a GUI which is very hard for the users to see what…

calculating the order of approximation in the Discretization scheme
Introduction: In this topic we will discuss on how to find out the order of approximation of your discretization scheme. The order of approximation can be determined by the truncation error term on the RHS. Mathematical Example: let us take this exampe 2nd order derivative for example. Let us try to derive a 1st…

Deriving the forth order approximation of the 2nd order derivative
Objective: The objective here is to derive the forth order approximation of the Skewed right hand side scheme and the central difference scheme using Taylors table and making sure that the stencil that we use is of forth order approximation. Numerical derivative to be decritized: `(del^2f)/(delx^2)` ---------------------------…
