<p>Dear FLASH Users,</p>
<p>I am in the process of trying to parallelise my simulations so
they run faster but I'm facing some issues in the calculations
when I'm running the calculations with more than one task. Indeed,
I see calculation artifacts at the junction of the tasks for all
values saved. Here is an example with my initial electronic
temperature and the same after some time step when I use two
tasks:</p>

moz-do-not-send="false" width="475" height="351"></p>
<p>Here is my setup line:<br>
<br>
./setup $currentSim -auto -2d +cartesian -maxblocks=300000 -nxb=16
-nyb=16 +hdf5typeio species=cham,targ +mtmmmt +uhd3t +mgd
mgd_meshgroups=1 threadBlockList=True <br>
</p>
<p><br>
</p>
<p>My submission to the cluster, the par file for the boundaries and
the Makefile.h I'm using are joined in the message.</p>
<p><br>
</p>
<p>Has anyone met similar issues and if so, how did you fix that
issue? Thank you in advance for your help.</p>
<p><br>
</p>
<p>Best regards,<br>
