* Use "epsilon" also for Brill-LindquistHEADmastereschnett2011-10-27
| | | | | | | | | | IDAnalyticBH has an "epsilon" parameter to smooth out singularites. This parameter should also be used in Brill-Lindquist initial data. Otherwise, moving puncture evolution of these data is not possible without an explicit smoothing step. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/IDAnalyticBH/trunk@183 6a3ddf76-46e1-4315-99d9-bc56cac1ef84
* The Kerr initial data (ineschnett2011-03-08
| | | | | | | | | | | | | | | | | | EinsteinInitialData?/IDAnalyticBH/src/Kerr.c) has a defect along the z-axis (that is, the spin axis of the hole). The three-metric (for instance) is not smooth across this axis, leading to discontinuities in second spatial derivatives near there. This appears to be due to overly crude safety measures protecting from division by zero when calculating this data. Tweaking these measures for more self-consistency leads to much smoother behaviour. I'm attaching a simple patch that fixes the problem at least for metric_type = physical. [Patch from Bernard Kelly] git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/IDAnalyticBH/trunk@179 6a3ddf76-46e1-4315-99d9-bc56cac1ef84
* Segfault with kerr initial data using IDAnalyticBHbmundim2011-02-28
| | | | | | | | | | | | | | | | | | | | Yosef's patch: If initial_data=kerr and metric_type=physical, IDAnalyticBH writes to psi[x-z] and psi[x-z][x-z] (it tries to set these GFs to zero) even if no storage is allocated. The problem is with the code: IDAnalyticBH_zero_CCTK_REAL_array(npoints, psix); etc.., which is only executed when the metric is physical. I was able to use the Kerr data with this patch, but just deleting the offending lines should be sufficient. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/IDAnalyticBH/trunk@178 6a3ddf76-46e1-4315-99d9-bc56cac1ef84
