Tapered grids
by Jakob Hansen 08 Nov '11

Hi, In order to change my simulations to use tapered grid, is all I have to do is set : Carpet::use_tapered_grids = yes in my parameter file, or is it more complicated than that? Cheers, Jakob

Einstein Toolkit Meeting *talk* reminder
by Frank Loeffler 07 Nov '11

07 Nov '11

Hi Please consider joining the weekly Einstein Toolkit phone call at 10 am US central time on Mondays. As usual, you can find instructions how to join on the following web site: http://einsteintoolkit.org/community/support/ I am happy to be able to announce that the Illinois Relativity group will present one of their recent papers within the next meeting: "Relativistic MHD in dynamical spacetimes: Improved EM gauge condition for AMR grids" [1]. I will not put another point on this week's agenda, to have the full hour available for this topic. We usually only use phone for these meetings, but this week we will utilize the scheduled EVO meeting "Einstein Toolkit weekly" [2]. The regular phone line will be opened as well, but don't expect to hear everyone if you use it. Frank Loeffler [1] http://arxiv.org/abs/1110.4633 [2] http://evo.caltech.edu/evoNext/koala.jnlp?meeting=eIe9esvvv8anaiatII

Hi Frank, I've been going through the paper this weekend, fixing some of the details like the three definitions of rho, etc. Have we decided to submit it to CQG? If so, I've got some style files and related packages to produce the suggested format. It definitely changes the look of the references a bit. If we have decided to publish there, I'll commit everything tomorrow night after I get a chance to read through the tests section.

Lorene local settings
by Luca Baiotti 01 Nov '11

01 Nov '11

Hello. Lorene is notoriously difficult to build (I mean, it is difficult to choose the appropriate local_settings to build it) and the thorn ExternalLibraries/LORENE is very helpful. However, I need to compile some non-standard code into Lorene, so I cannot use ExternalLibraries/LORENE. (Or can I?) So I need to compile Lorene by myself but I would like to use the settings determined by ExternalLibraries/LORENE. In ExternalLibraries/LORENE/LORENE.sh I found the lines: cat > local_settings <<EOF CXX = ${CXX} CXXFLAGS = ${CXXFLAGS} ${CPP_OPENMP_FLAGS} CXXFLAGS_G = ${CXXFLAGS} F77 = ${F77} F77FLAGS = ${F77FLAGS} ${FIXEDF77FLAGS} F77FLAGS_G = ${F77FLAGS} ${FIXEDF77FLAGS} INC = -I\$(HOME_LORENE)/C++/Include -I\$(HOME_LORENE)/C++/Include_extra \$(addprefix -I,${GSL_INC_DIRS}) RANLIB = ${RANLIB} # We don't need dependencies since we always build from scratch #MAKEDEPEND = ${CXX_DEPEND} \$(INC) \$< ${CXX_DEPEND_OUT} && mv \$@ \$(df).d MAKEDEPEND = : > \$(df).d DEPDIR = .deps FFT_DIR = FFT991 LIB_CXX = ${LIBS} LIB_LAPACK = ${LAPACK_LIBS} ${BLAS_LIBS} LIB_PGPLOT = LIB_GSL = ${GSL_LIBS} DONTBUILDDEBUGLIB = yes EOF but I could not make out directly the values of all the parameters. Is there a way to print out the local_settings file produced and used by ExternalLibraries/LORENE? Any help is welcome. Cheers, Luca
