Hi,
I finished yesterday with the equations and some pics, I think
is pretty cool
.
I hope you see it

Dear Akshay,
welcome to the CAE Linux forums. It is always nice to see such an interest for open-source CAE codes, especially from experienced users!
To answer your questions:
1. CAELinux include codes that can be compared to Ansys or Abaqus in the field of thermo-mechanical simulation (without piezo though...) for example Salome-Meca (Code-Aster) or Calculix offer both a rich set on modelling options. But at the moment, there are no code that can really support the comparison with LS-Dyna or Abaqus Explicit: Dynela and Impact are explicit dynamic codes, but they do not have the same level of maturity compared to commercial codes. In the field of CFD, OpenFOAM is really powerfull and expandable, but is still rather complex to use for novice. The latest release of Code-Saturne (will be included in CAELinux 2008) is, in my opinion, very close to what can be found in commercial codes and is really efficient and simple to use in practice. For the pre-processing / meshing, one can use either Salome, GMSH, Netgen or Tetgen, but even if Salome is rather close the the interface found in commercial codes, its meshing algorithms still need to be polished a bit to sustain the comparison.
At the moment, what the open-source codes are lacking the most is a nice GUI based block-structured mesher that could import CAD geometry (something like ICEM..).
2. The answer is clearly YES. If you look at results of the poll on the left, you will clearly see that, from the user's point of view, the most important point to improve in CAELinux is tutorial & documentation. So if you are willing to contribute, do not hesitate! It will be highly appreciated. If you want to publish your work, you can directly add a page or section in the wiki at www.caelinux.org.
Also creating a flash video tutorial is simple and fun with the help of Wink: www.debugmode.com/wink/download.php
I am looking forward to read your tutorials soon
