I'd take one of the test file
Cactus/arrangements/CactusNumerical/Dissipation/test/test_ah.par which
already uses IDBrillData and ML_BSSN and combine it with a more useful
parameter file (say Cactus/par/ks-mclachlan.par) to have something more
like an actually useful simulation.

Note that IDBrillData is very much unused by now and requires some
tricks to get to work with McLachlan (see the comments in test_ah.par).

Yours,
Roland
