Installing pyFoam for OPENFOAM

PyFoam is a scripting language for OpenFOAM.Being similar to python the script can be used to make changes in FOAM case directories.

Below given are the steps for imstalling PyFoam on your linux machines:

STEP 1)

Downaload the latest version of "PyFoam" from the link given below:

http://openfoamwiki.net/index.php/Contrib_PyFoam

STEP 2 )

It will be a tar file. Untar the tar file in the folder of your choice

STEP 3)

Open the command terminal and go to the folder in which you have untared the pyFoam file.

STEP 4)

Using Synaptic Package manager install these two library files which are needed for pyFoam

libboost -dev

libboost -doc

STEP 5 )

In pyfoam folder you will see a set up file named "setup.py"

In the terminal window type the command :

python setup.py install

STEP 6 )

You are done with installation.

To check your installation in the terminal type "python"

Now type :

import PyFoam

import PyFoam.FoamInformation

print PyFoam.FoamInstallation.foamTutorials()

This command should produce a output showing the openfoam tutorials directory.

GRID PRO-Ultimate tool for meshing

GridPro is an automatic, object-oriented, multiblock grid generator.
It provides users with a highly efficient, interactive capability to build topology, edit surfaces, set CFD boundary conditions, view grids and launch the grid generator.
Users interact with GridPro through the Az-Manager, an easy-to-use, dynamic 3D environment that combines a powerful scripting language with a user-friendly GUI front end. Automated processes minimize the amount of manual manipulation required to generate a grid, reducing errors in grid specification.
GridPro automatically creates templates of your grids to permit fast optimization to meet specific criteria.
To ensure that the highest quality grids are generated, the software engine incorporates a unique algorithm using advanced mathematical techniques. The algorithm optimizes each grid so that every element is smooth and orthogonal throughout the volumetric region under consideration

OpenFOAM 2.1.1 release

The latest version of OpenFOAM 2.1.1 was released on 31/5/2012.Bugs are removed and a lot of new features have been implemented after the 2.1.0 release.
To download OpenFOAM 2.1.1 visit the openfoam website on this url:
http://www.openfoam.org/download/

You can also download openfoam from synaptic package manager by simply typing in the terminal OpenFOAM.

P.S: In case it doesn't show up try fixing the repository by adding it manually in  synaptic  package manager > settings > repository > othersoftware and add the required openfoam repository

Genius CFD stuff.....from academic to animation industry--Ron Fedkiw

Finally CFD has also entered the animation industry. Prof .Ron Fedkiw has used Cfd codes to make animations look real.His real life animations have been earned him several credits,some of his works have been used in films like "Terminator 3", "Star wars".etc..etc.

You can find more information on Prof.Ron Fedkiw and his (wonderful) work on this website:

Dutch OpenFOAM User Group (DOUG)

Dutch OpenFOAM user group(DOUG) these are a bunch of enthusiastic members who use OpenFOAM to carry out CFD simulations and have formed a team which handles different domains of fluid flow which includes Combustion ,Magneto Hydrodynamics,multiphase flows and marine applications.
Any one can join this 'Special interest group (SIG)' and get your self equipped with their seminars and various other updates/activities on OpenFOAM.

SPOKEN TUTORIALS

Spoken Tutorial is the initiative of IIT BOMBAY for creating awareness and use of Free and Open source softwares for science and engineering which is funded by MHRD(Ministry of human resource development). Spoken tutorials are a kind of self learning techniques where the user can learn a software with the help of audio and video tutorial.There are various FOSS (Free and Open Source Softwares) available on the website of spoken tutorial.

CAE LinuX

It is dedicated to the computer aided engineering Linux distribution CAElinux.
Thanks to Open Source, now you just need to insert the CAELinux LiveDVD in your computer to turn it into a professionnal CAE / FEA / CFD workstation: no licence and even no installation is required.
Based on the open-source CAE softwares
1) Salomé
2) Code_Aster
3) Code_ Saturne
4) OpenFOAM 
5) Elmer
you can load your CAD geometry,  generate a computation mesh and setup your simulation problem in a few minutes.
Then you can simulate incredibly complex physics with the open-source FE & CFD solvers Code_Aster, Code-Saturne, OpenFOAM & Elmer: non-linear thermo-mechanics, coupled fluid-structure dynamics, seismic / non-linear explicit dynamics, contacts, visco-plasticity, fluid dynamics, heat exchange, convection heat transfer and radiation in other words nearly all physics problem can be addressed with the integrated solvers!! Then reload your results files in post-processing applications like Salomé, GMSH or Paraview to visualize your data in 3D... And don't forget all these features are based on open-source / free softwares, so now you don't have to pay for any expensive licenses and if you want, you can even improve it.
