If you are dealing with some delicate computations that require you to investigate the values of fields in some cells (I use this for debugging), there is a way to do this in Paraview:

View->Selection Inspector

Create Selection

Selection Type: Thresholds

Check the box: Invert selection

Scroll down to the Display Style subwindow and select Cell Label

Check the box: Visible

Choose: "p" for pressure...

If you are visualising a bunch of .vtk files that were generated separately from the standard fields in OpenFOAM, and if you are a lucky person like me at this point (your time steps are constant), there exists a simple way to visualize the files alongside OpenFOAM data:

1) Open the OpenFOAM case as usual.
2) Open the .vtk files. The files have to be named appropriately to be read as time-dependent data: someName-001.vtk, someName-002.vtk, guess what is the next name. ...

This blog post will try to detail and complement the OpenFOAM 2.0.1 building process on old machines, where my test case was with two Ubuntu 8.04 - one i686 and one x86_64 - in two separate virtual machines with 1.6GiB of RAM and 4 processors each.

Rant #3 - This one is about the novel "The Hitchhiker's Guide to the Galaxy". Unfortunately I've never read the whole novel, but my mind crunched some numbers based on what I read on Wikipedia. You can see the summary here at Wikipedia. For more on the plot, see Phrases from The Hitchhiker's Guide to the Galaxy
