Absorbing Boundary Conditions
16.01.2008 at 19:24:52
 
These are animated snapshots of sample output from my time-domain wave equation modelling programme that implements my latest absorbing boundary conditions technique. The proposed technique allows for a computationally efficient numeric solution of Cauchy problems, and in terms of computational complexity it rivals existing techniques such as Perfectly Matched Layers. The method can have a broad range of applications to modelling wave phenomena in Physics and Engineering.
 
Those interested in joining the research are welcome to send their suggestions to me. The research has a very attractive commercial stimulus.

And now I have coupled my ABC with the wavenumber-domain methods (those methods apply sundry differential operators in the wavenumber domain, wrapped in the Fast Fourier Transform).
 
Next step: 3D...
 
Even the 2Dmath was formidable (though very efficient computationally) but I expect the 3D formulae  to be ... an order of magnitude more complicated but still very attractive computationally!  Grin
