Steps The model recieved was checked for geometry errors. The errors were identified using 'Checks Manager' and corrected. The model was sliced into 2 halves and one half was deleted. The other half was corrected for geometry errors and then after the completion, it was mirrored to get the other half. Now the meshing is…

Blockmesh Drill Down Challenge In this challenge we are asked to generate a Blockmesh file of the above given figure in OpenFoam and simulate the flow through a backward facing step. Then we are to post process the result and check the effect of grading scheme on velocity. As given in the video no 37, we are deviding the…

Steps The model recieved was checked for geometry errors. The errors were identified using 'Checks Manager' and corrected. The intersecting parts was dealt with. Now the meshing is initiated by setting the values in the 'Mesh Parametres' option and 'Quality Criteria' option. Volumetric Mesh option was selected and the…

We are to derive 4th order approximation of the 2nd order derivative with respect to central, skewed right sided and skewed left sided difference. Then we have to find the absolute error between the above differences for analytic function exp(x)*cos(x). We begin this project by first giving the explanations for central,…

Steps The model recieved was checked for geometry errors. The errors were identified using 'Checks Manager' and corrected. The model was sliced into 2 halves and one half was deleted. The other half was corrected for geometry errors. Then the middle surface was extracted using offset option and a different PID was set…

The primary aim of this project is to simulate the flow through a square cross section pipe. The solver used here is 'simpleFoam'. The velocity is assumed to be 1m/s. The model is laminar flow model.   Steps  The terminal is opened in linux OS. The terminal is opened in linux OS.  Using the necessary commands,…

Steps The model recieved was checked for geometry errors. The errors were identified using 'Checks Manager' and corrected. Then the middle surface was extracted using offset option and a different PID was set for it. The alignment of the holes were checked and corrected. Then the middle surface was checked for geometry…

Flow Through Nozzle Introduction to Nozzle A nozzle is a device designed to control the direction or characteristics of a fluid flow (to increase velocity) as it exists (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow…

We are solving 2d heat conduction equation in this project. We are doing it in Steady state and Transient state conditions. The iterative techniques include Gauss Siedal, Jacobi, SOR methods.    Steady State 2D Heat conduction  Main Equations We know 2D heat conduction equation is given by  `alpha((del^2T)/(delx^2)…
