Hi All,
I have been working on reproducing the results in the paper:
The Einstein Toolkit: A Community Computational Infrastructure for Relativistic Astrophysics (arXiv: 1111.3344v1 {gr-qc] 14 Nov 2011)
and others as a way to teach myself how to use the Einstein Toolkit and to test out my home-built cluster computer.
I am currently working on the non-rotating TOV neutron star collapse into a BH. It works well up until it fails trying to convert conserved variables into primitive variables in grhydro (see attached tovCollapse.out file). I have tried adjusting the atmosphere parameters (specifically GRHydro::rho_abs_min = 1.e-8, up from 1.e-10)., as per the suggestions in the grhydro documentation, which has helped, but I think the conversion is failing now very near where the AH will/is forming.
I have included my parameter file for the simulation (I lowered evolve K from 98 to 80 just to accelerate the collapse process).
Any help anyone can give would be greatly appreciated.
Sincerely, Tony...
