Greetings to all!

This is an open letter to all OpenFOAM users that wish to contact me asking about problems they are having with OpenFOAM.

First of all, please ask in the public forum. There is a good forum thread that explains how to get: http://www.cfd-online.com/Forums/ope...-get-help.html

Automated scripts for building gcc 4.4.x and 4.5.x for using with OpenFOAM 1.7 series

Posted September 26, 2010 at 10:35 by wyldckat
Updated April 21, 2011 at 21:08 by wyldckat (Added 4th version of the scripts)
Tags gcc, openfoam

This blog post is meant to centralize my efforts for providing gcc build scripts to the OpenFOAM community. It provides build scripts for gcc 4.3.x, 4.4.x and 4.5.x series.

NOTE: If you don't have internet on the computer where you want to run this script, you can still run these scripts, because they will provide you with instructions on which files to download and where to place them!

These scripts are based on the scripts provided with the patches for cross-compiling...

Building OpenFOAM1.7.0 from source

Posted August 25, 2010 at 17:08 by maysmech

Needful installation to ./Allwmake in in the folder $WM_PROJECT_DIR/OpenFOAM-1.7.0:installation several packages, and the one in particular that you are missing is build-essential.
This is a command line that will install most of the necessary (and some possibly unnecessary) packages for building OpenFOAM and ParaView:

Code:
sudo apt-get install binutils-dev flex bison git-core build-essential python-dev libreadline5-dev wget zlib1g-dev cmake libpng12-dev libxt-dev libxi-dev libxrender-dev

Flux computation in unstructured grids

Posted July 16, 2010 at 10:49 by praveen (CFD, Numerical Analysis, Scientific Computing)

Consider finite volume scheme on unstructured grids for the Euler equations.

Let n=(n_x,n_y,n_z) be normal to a cell face and whose magnitude is equal to face area. Let Q be the conserved vector. The finite volume update equation using forward Euler time discretization is

Q^{n+1}_j = Q^n_j - \Delta t \sum_{k \in N(j)} F(Q_j^n, Q_k^n, n_{jk})

Here n_{jk} is a normal vector pointing from current cell "j" into the neighbouring cell...
