Whisky: thornlists, parameter files and examples

Here are a few thornlists containing ever greater numbers of thorns. For each you must remember to change the login name as detailed on the download page.

WhiskyShock.th contains the minimal list of thorns required to run the code. This code will run the simple shock tube test and will also do evolution of the hydro on a fixed spacetime. Only the ideal gas EOS is supplied.

WhiskyRotNS.th adds the thorns necessary to make RNSID run. Again the spacetime will be fixed. Only the polytropic EOS can be used.

WhiskyTOV.th adds the thorns necessary to evolve the spacetime using BSSN.

WhiskyIVP.th adds the thorns necessary to solve the IVP problem if the initial data does not satisfy the constraint equations. This requires BAM_Elliptic, BAM_VecLap and some of the CactusElliptic arrangement. The use of BAM_Elliptic is not totally straightforward; see the parameter file below or the ThornGuide.

WhiskyAll.th contains all the thorns that might be useful in an evolution. Note that not all of these thorns are generally accessible, so some may need to be commented out.

Parameter files

These are sample parameter files corresponding to the above thornlists. None of them are actually test cases as they're too large and actually do some (vaguely) useful evolution.

WhiskyShock.par does a diagonal shock tube using PPM reconstruction and the Marquina solver.

WhiskyRotNS.par uses RNSID to give rotating neutron star initial data which is then evolved with the spacetime held fixed.

WhiskyTOV.par uses RNSID to give TOV star initial data which is then evolved using a dynamical spacetime.

WhiskyIVP.par uses BAM to solve for the constraints given rotating neutron star initial data (this is unnecessary but illustrative). Note the grid size; BAM has various restrictions on grid size and processor number. For more details, see the ThornGuide.
