Dear fellow ETK users,
I implement a rotating BH in Kerr-Schild coordinates without using the puncture method. As the hydro code crashes due to the ring singularity I somehow have to excise the respective region of the grid. I also tested a Schwarzschild BH in isotropic coordinates, but there also the hydro crashes due to the singularity at the origin.
Do you have any recommendations which excision tool I could use?
Thank you for your help.
Cheers, Gela
