<div dir="ltr">Hi, I was wondering if anybody could help me spot the problem(s) in (possibly) my parameter file?<br><br>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):<br><br><a href="https://gist.github.com/konrad-topolski/1f292fbb234232e68dd76e4fc784e481" target="_blank">https://gist.github.com/konrad-topolski/1f292fbb234232e68dd76e4fc784e481</a><br><br>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:<br><br>CarpetMask::excluded_surface [0] = 0<br>CarpetMask::excluded_surface_factor[0] = 1.0<br>CarpetMask::excluded_surface [1] = 1<br>CarpetMask::excluded_surface_factor[1] = 1.0<br>CarpetMask::excluded_surface [2] = 2<br><div>CarpetMask::excluded_surface_factor[2] = 1.0</div><div><br></div><div>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.</div><div><br>Hence the question, how to set up the puncture tracker, AHFinderDirect and CarpetMask correctly?</div><div>I also set up the target masses instead of the bare ones.</div><br><div>I am currently playing around with some options, but in case I don't get anywhere, I would much appreciate any help. <br></div><div><br></div><div>Best regards</div><font color="#888888"><div>Konrad Topolski</div></font></div>
