<div>Hi All,</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>I am new to FLASH4 therefore I apologize in advance if this issue has been already discussed ( I was not able to find it in the FLASH user archives though).</div>
<div><br>
</div>
<div>I had no problems running the Laser Slab example in 2D, however when I run the 3D case the simulation ended up with the error reported below, indicating negative electron temperature was generated.</div>
<div><br>
</div>
<div>"</div>
<div>
<div> *** Wrote checkpoint file to lasslab_hdf5_chk_0007 ****</div>
<div>….</div>
<div>…. </div>
<div> Driver_abort called. See log file for details.</div>
<div> Error message is [ed_traceBlockRays3DRec] ERROR: Tele <= 0 for a cell (target)</div>
<div> Calling MPI_Abort() for shutdown in 2 seconds!</div>
<div> </div>
<div>application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0</div>
</div>
<div>"</div>
<div><br>
</div>
<div>The setup command I used for the simulation is:</div>
<div><br>
</div>
<div><br>
</div>
<div>./setup.py -auto LaserSlab -noc -3d +pm4dev +hdf5typeio -nxb=16 -nyb=16 -nzb=16 +mtmmmt +laser +mgd +uhd3t species=cham,targ mgd_meshgroups=6 -parfile=example3d.par -objdir=obj_LaserSlab3D</div>
<div><br>
</div>
<div>None of the files has been modified from the original distribution.</div>
<div><br>
</div>
<div>Any ideas about what I could be missing?</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
