Hi, I was wondering if anybody could help me spot the problem(s) in (possibly) my parameter file?
I am trying to run a BBH simulation with mass ratio = 3. The parameter b=3 and the punctures were set at +3 and -1 on the x axis (as I understand the setup requires, so that the center of mass is at 0). I set up the CarpetGrid refinement domains accordingly. The simulation runs for about 8000 steps and ends with an error concerning the grid, which I put here (error log and parameter file attached):
https://gist.github.com/konrad-topolski/1f292fbb234232e68dd76e4fc784e481
The differences between this parameter file and the one originally provided with Einstein Toolkit was that I had removed any reflectionsymmetry180 and I commented out the Carpet Mask variables concerning the surfaces, i.e I simulated without:
CarpetMask::excluded_surface [0] = 0 CarpetMask::excluded_surface_factor[0] = 1.0 CarpetMask::excluded_surface [1] = 1 CarpetMask::excluded_surface_factor[1] = 1.0 CarpetMask::excluded_surface [2] = 2 CarpetMask::excluded_surface_factor[2] = 1.0
I did so because there was some weird behaviour with Surface mask location - it correctly localized the puncture 0 (at +3), but couldn't locate the puncture 1 (at -1) - it said it was at [e^273, ..., ...] etc.
Hence the question, how to set up the puncture tracker, AHFinderDirect and CarpetMask correctly? I also set up the target masses instead of the bare ones.
I am currently playing around with some options, but in case I don't get anywhere, I would much appreciate any help.
Best regards Konrad Topolski
