Reimann curvature tensor
« on: 13/02/2014 15:46:50 »
Are there any sites that may have software implementations of these calculations. I am wanting to develop a software program to carry out calculations.

I take it you have Wolfram Mathematica 7.0 and MATLAB_R2012b

Neither. Although the non-professional version of mathematica is not too expensive I doubt it would be suitable for my needs. Matlab I used years back but it is too pricey. I want to write my own routines but was looking for enough info to help me write it. Being lazy really.

It's not an easy task and depends on what you're trying to do with these calculations.  Check out the various references in: http://en.wikipedia.org/wiki/Numerical_relativity

You can also find textbooks on the subject. 

Since you're solving the equations numerically on discrete grids, you have to get the geometry right and make sure the solutions are stable, both of which are non-trivial problems.

Oh I do realize the daunting nature of the task. I am tackling the partial gravitational cancellation problem which is also not trivial so I may as well go the whole way.
