Posted April 4, 2011 at 05:37 by vishal

Hi All,

I know its really painful to find correct formulas for calculation of k and Epsilon values, If any of you are dealing with atmosphetic flows. (Exponential valocity inlet or power law). I would recommend to "atmBoundaryLayderInlet" conditions located at

OpenFOAM1.7.1/scr/turbulanceModels/incompressible/RAS/derivedFvPatchFields/atmBoundaryLayerInletEpsilon/atmBoundaryLayerInletVelocity.c file.

over list of values at inlet and...

Blast from the past: installing OpenFOAM 1.5 in modern Linux boxes

Posted April 2, 2011 at 08:23 by wyldckat
Updated July 30, 2012 at 16:14 by wyldckat (Added v2)

Here we are in 2011 and we need good oldie OpenFOAM 1.5 to work in our latest über advanced Linux box.
Our trusty gcc compiler nowadays comes in flavours 4.4.x, 4.5.x and 4.6.0 was released a little while ago.
The official release of OpenFOAM 1.5 latest compatible gcc was 4.3.x. And you think to yourself: now what do I do?

Well, not to worry! After a request from the forum user kurne, I rolled up my sleeves and made a cookbook script of a hybrid OpenFOAM 1.5 with 1.7.x script...

Updated October 31, 2015 at 09:25 by wyldckat (added more links)

This is a rough list of informations to be compiled and posted on on a page about running OpenFOAM in parallel. If someone picks up on this and wants to start the article in the wiki, be my guest. Leave a comment pointing to the wiki page, so we can cooperate

List of already catalogued applications on the wiki for pre/post processing for parallel mode:
Yet to be catalogued:
  • redistributeMesh
  • renumberMesh

Linking FLUENT with visual C++ (Tested on 32Bit OS)

Posted February 12, 2011 at 12:10 by Amir
Updated September 14, 2012 at 09:26 by Amir

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....

openFoam 1.7.1 IcoDyMFoam CODE

Posted January 26, 2011 at 13:29 by McCarra (Dynamic Mesh App's)

This entry is related to the changes needed to apply in icoDyMFoam code to turn it into a dynamic mesh solver. Further entries will determine the changes to the ancillary files ( correctPhi.H, readControls.H ...) which are needed to prepare it for compilation.

The objective is to identify in the code of pimpleDyMFoam what are the lines related to the mesh motion. This code is what should be added to original icoFoam to make it run with dynamic meshes. To do this pimpleDyMFoam is compared...
