In general, there are 2 different ways to link FLUENT with VC++. In both methods, we need to add fluent to system path which can be easilly done via executing "setenv.exe" which is in FLUENT installation folder.

1) non-permanent method:

In this method, we need to launch FLUENT by VC++ command prompt (which can be found in tools folder of VC++) by simply typing fluent.
In this method, we have to launch FLUENT in this manner whenever we want to compile a UDF....

At convergence, the following should be satisfied:

• All discrete conservation equations (momentum, energy, etc.) are obeyed in all cells to a specified tolerance OR the solution no longer changes with subsequent iterations.
• Overall mass, momentum, energy, and scalar balances are achieved.
• Monitoring convergence using residual history:
• Generally, a decrease in residuals by three orders of magnitude indicates at least qualitative convergence. At this point, the major flow features should be

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...

OpenFOAM has four methods of decomposition:
(1) simple
(2) hierarchical
(3) scotch
(4) manual

"Scotch decomposition requires no geometric input from the user and attempts to minimise the number of processor boundaries."(for more information refer OpenFOAM website)

We tried to compare "simple" and "scotch" methods. These methods were verified for a test case using similar processor inputs:

Both...
