<div dir="ltr">Hi Gabriel,<div><br></div><div>I have encountered (and am to some extent still trying to understand) a similar, possibly the same, issue (also with FLASH 4.8).

It would also be useful if you try using +noio to determine if you have an HDF5 issue, and -debug to provide a traceback if an exception is raised.<br><br>It's interesting this happened for you just changing distributions.

<p>Dear all,</p>
<p>I have been using FLASH for a while in Ubuntu 18, and am moving
now to use the linux distribution OpenSUSE. However, when running
flash in parallel mode, I am encountering the following problem.</p>
<p>I am testing the LaserSlab example, with FLASH4.6.2, using
hdf5-1.10.7, hypre-2.11.2 and openmpi-4.0.5 (same as I used in
Ubuntu 18). <br>
</p>
<p>I am launching the simulation by using <i>"./setup -auto
LaserSlab -2d +cylindrical -nxb=16 -nyb=16 +hdf5typeio
species=cha</i><i><br>
</i><i>m,targ +mtmmmt +laser +uhd3t +mgd mgd_meshgroups=6
-parfile=example.par" </i>then moving to the <i>object</i>
directory, using <i>"make -j"</i> and after SUCCESS running "<i>mpirun
-np 3 flash4"</i>. <br>
</p>
<p>Now, this is what I used to do in Ubuntu, but what I am finding
in this case is that the calculation is initialized, but after
printing <i>"Initial dt verified" </i>nothing else happens. The
code does not move forward. I can see that the chk_0000 file has
been generated, but not the plt_0000.</p>
<p>Has anyone encountered this problem before? Does anyone have any
suggestions on how to fix it?</p>
<p>Best,<br>
</p>
