<div>sorry for the messages before, hopefully the mail is now small enough, but i thought that adding a plot might explain better what i mean..</div><div><br></div>Hello all,<br><div class="gmail_quote"><div class="HOEnZb">
<div class="h5"><div class="gmail_quote"><div><br></div><div>i recently read the Reisswig et al. 2012 paper and started trying to switch to cell-centered grid in order to be able to use the LSUThorns/Refluxing thorn. i am trying to simulate BH+torus systems and due to the size of the torus its hard to have it contained within a refinement level, so i thought that using a cell-centered grid in order to use refluxing might improve results..</div>
<div><br></div><div>i however run into problems getting the hdf5 output of 3D grid frundtions to work...</div><div><br></div><div>using the static_tov_cc_rf.par file from the Refluxing trunk, i get weird output in the mesh at the reflection boundaries (the par file uses octant mode)..</div>
<div><br></div><div>i am using the following parameters for CarpetIOHDF5:</div><div><br></div><div><div>IOHDF5::out_every = 256</div><div>IOHDF5::one_file_per_group = no</div><div>IOHDF5::output_symmetry_points = no</div>
<div>IOHDF5::out3D_ghosts = no</div><div>IOHDF5::output_ghost_points = no</div><div>IOHDF5::out3D_outer_ghosts = no</div><div>IOHDF5::output_boundary_points = no</div><div>IOHDF5::output_buffer_points = no</div>
<div>IOHDF5::compression_level = 9</div><div>IOHDF5::use_checksums = yes</div><div>IOHDF5::out_vars = "</div><div> HydroBase::rho</div><div> HydroBase::press</div><div> HydroBase::eps</div>
<div> HydroBase::vel</div><div> ADMBase::lapse</div><div> ADMBase::metric</div><div> ADMBase::curv</div><div> GRHydro::scon</div><div>"</div></div><div><br></div><div>the simulations seems to work fine, so is the carpetiohdf5 thorn not suitable for cell-centered output? another effect (that might be output related) is that the different refinement levels are shifted (i'll attach a file showing this in the TOV from the par file (i added extra refinement levels to illustrate the effect) as well as a plot of the density in the torus)...</div>
<div><br></div><div>are the specific parameters for cell-centered hdf5 output or other thorns that could take care of that?</div><div><br></div><div>best wishes,</div><div><br></div><div>Vassili</div>
