Reading heat flux into tecplot from openfoam

Posted November 7, 2013 at 16:29 by cm_jubayer

Tecplot cannot read heat flux data from OpenFOAM directly with the OpenFOAM data loader in Tecplot. Below are the steps that I use to read the heat flux data or any other data that is not readable by the OpenFOAM data loader.

1. Open your data in paraview.

2. Export the data from paraview using File>Save Data. This will give you a csv file.

3. Now open the csv file in excel and rearrange the data so that we have variable name in the first row as...

So there present oscillations, they were caused by second order schemes. I'll simulate it on upwind later.

The differences in p fields are showed here:

OpenFOAM Installation for Multiple Users

Posted March 9, 2013 at 09:26 by Hisham (Notes for OpenFOAM!)
Updated March 10, 2013 at 10:47 by Hisham

If OpenFOAM was installed on a single user account using the OpenCFD binaries then for another user to have access to it is very simple. All one needs to do is to add an alias of the installation in the new user's .bashrc file

Code:
OFver='source /opt/openfoamver/etc/bashrc'
If, on the other hand, OpenFOAM (or OpenFOAM-ext) was compiled on a user account (say the user name is MrX) and a new user (MrY) wants to use the same installation, then:

1. MrX must make sure...

Hey, Dude, be careful with liftDir/dragDir in controlDict

Posted February 19, 2013 at 05:41 by skeptik (CFD notes)

When U is changed due to angle of attack you should change controlDict in libForces section.

So, what can you get when you have proper controlDict

U=56.4, Re=1.6e6

OpenFOAM with ICC - Intel's ICC is "allergic" to AMD CPUs

This is yet another one of my "rants on my blog" I do once in a while.

So today I was trying to reproduce this report: http://www.openfoam.org/mantisbt/view.php?id=590 - I was curious about this, because ICC is known for having great optimization on Intel processors (or at least it had in the past), as well as being completely free for non-commercial use on Linux.

The detail here is that I don't have an Intel CPU on my home computer. I've got an AMD 1055T x6 ...
