Hi Jose,

What sort of output do you want to visualise?  Cactus thorns typically output "lightweight" information such as BH trajectories and waveforms as ASCII, and more heavyweight data -- like gridfunctions -- as HDF5.  For the trajectories (from thorn Puncture Tracker) and waveforms (from Multipole) you can use gnuplot or anything that can read standard ASCII output to visualise them.  For gridfunctions in HDF5 format, I think the easiest way to get started is to use VisIt, for which there is a Carpet plugin (though installing VisIt is sometimes not so easy!).

Does anyone know if the Carpet plugin is distributed with VisIt yet?  I believe that was the intention.
