Tensorial is a general purpose tensor calculus package for Mathematica 5.0 or later. Easy to learn and convenient for students and researchers. The authors are Renan Cabrera,
University of Windsor, Canada, David Park, and Jean-François Gouyet,
Ecole Polytechnique, Palaiseau France. Some of the features of Tensorial 4.0 are:
• Complete freedom in choosing tensor labels, indices and base indices.
• Flavored (colored or annotated) indices for various coordinate systems.
• Differently flavor indices may have different dimensions and base index sets.
• Minimum keystroke tensor input and formatted output that can be copied and pasted.
• Detailed set of index manipulation routines.
• Easy routines for setting tensor values or rules and expanding tensor sums and arrays.
• Zero tensors balance free indices, behave like zero and expand to zero arrays.
• CircleTimes and dot product routines.
• Routines to declare and apply tensor and tensor expression symmetries.
• Kronecker, generalized Kronecker and Levi-Civita routines.
• Partial, covariant, total, absolute and Lie derivative routines.
• Christoffel, Riemann, Ricci, Einstein, Weyl and scalar curvature routines.
• Conversions from coordinate basis to orthonormal basis.
• Dot mode routines to convert from index notation to Mathematica array form calculations.
• Blends naturally with the normal Mathematica notebook interface and kernel routines.
• Complete documented Help with individual pages and examples for each command. Additional tutorial notebooks.
The following pdf file illustrates a calculation performed with Tensorial. The example corresponds to exercise [22.32] in Penrose's Road to Reality , generation of the Laplacian operator on the surface of a sphere. Penrose classifies the exercise as 'not to be undertaken lightly'. Tensorial Example
Tensorial 4.0 has now been converted to Mathematica Version 6.0. The only
deficiencies are that the special palette based copy and paste does not
completely work and several of the Example notebooks use DrawGraphics and
this has not yet been converted to Version 6.0. However, all the basic
functionality works along with normal copy and paste.
If you purchase Tensorial you can download either the pre 6.0 Version or the 6.0 version, or both.
You may wish to check the site occasionally for updates. A section in the Help Introduction gives a history of the major additions and changes in usage. A copy of the installation instructions is included in the downloaded zip file.

The following is a documentation package for Tensorial 4.0 for those who wish to
examine the package before purchasing. It contains all of the documentation and
examples in evaluated form but lacks the actual package. There is also a Mathematica
Slide Show that illustrates some of the main features. The evaluated documentation
occupies about 29 MB. The downloaded zip file is about 3 MB. To install it just
unzip into your personal Mathematica\Applications folder and rebuild the Help Index.
This is for Mathematica 5.2.

There is now a TensorCalculus5 version of Tensorial that works in Mathematica Version 6+. It contains the Mathematica paclet type documentation, a style sheet and a useful Tensorial Palette. It can be purchased and downloaded at the same links used for Tensorial 4. If you already own Tensorial 4 you can simply update there if you have saved the link, or contact us.
A number of Tensorial 4.0 Mathematica notebooks on various topics in physics are available at Renan's web site Tensorial 4.0 Examples. There are also pdf files of the notebooks so that you can view examples before deciding on purchasing Tensorial. Some of the notebooks would also require DrawGraphics.
TContinuumMechanics2 is a package by Jean-François Gouyet that adds additional commands
to Tensorial 4.0 for working in continuum mechanics. It works through the material
in the well known Flugge text on continuum mechanics as way of illustration. There
are two versions of the package, one for Mathematica Version 6, and one for
Version 5.2 and earlier.The 5.2 package requires
the 5.2 version of Tensorial 4.0 and the 5.2 version of DrawGraphics to
generate the graphics in the Flugge notebooks.The Version 6 package works
with the Version 6 Tensorial and Presentations, the follow on to DrawGraphics.
On purchase you may obtain either or both packages but it is best to have only
