<div>My problem is: the simulation gifs of the Wave Equation and
Heat Equation notebooks on the tutorial folder are not showing
correctly.</div>
</div>

<p>So I just clicked through the heat equation notebook. The cell
that ends with:</p>
<p>## play animation<br>
from IPython.display import HTML<br>
HTML(anim.to_html5_video()) #playback option 1<br>
#HTML(anim.to_jshtml()) #playback option 2</p>
<p>Played an animation for me. Initially, there is a spike at the
center of the grid, and it evolves to become flat. (It also
printed a deprecation warning about the "close_event" function,
whatever that is).</p>
<p>Did you click through to this cell or did you stop at the one
before? Because the one before it just displays a still image.</p>
<p>The WaveEquation also worked for me by just clicking through the
cells in order.<br>

<div>I'm trying to understand how Cactus works, so I ran every
cell in the notebook while looking at the Terminal and seeing
how each file is created and its contents. </div>
<div>The problem comes when I finally run the simulations, which
take a while. </div>

This happens in seconds for me.<br>

<div>So after the running is complete, there's this section
called "Extract data from hdf5 files".</div>
<div>The files exist, as I have previously checked, but the time
steps array is actually a [0,0] array in the heat equation,
and a very random array in the wave equation. </div>
<div>In both cases, when plotting the simulations, the solution
does not change from the initial condition.</div>
</div>
</blockquote>
Did you modify the cells from the original tutorial? Because this
all just worked for me.<br>

</div>
<div>I tried to open the data files to see if I could understand
what was going on but I'm unable to open these kind of files,
and Cactus being a black box leaves me helpless to see where
the mistake is coming from.</div>
</div>
</blockquote>
<p>So I disagree that Cactus is a black box since it is open source
and the purpose of these tutorials is to show how it works... but
it's a very big non-black box which can be overwhelming.</p>
<p>I think your problem is the hdf5 files, not Cactus. Hdf5 is a
file format that Cactus uses. You can open them with commands like
h5ls, or Python's h5py library (which the notebook provides some
examples of usage).<br>

</div>
<div>I want to work on the problems at the end of these
notebooks, but not correctly seeing the solution makes me
think there's something wrong since the beggining, and I have
not changed anything else from the initial notebook.</div>
</div>
</blockquote>
<p>So I'm not 100% sure what's going on, but I suspect you've either
not clicked far enough or you have modified the notebook. Please
check and let me know.</p>

<div>I have a small question. I'm having a bit of
trouble with some tutorial notebooks, in particular
the Heat Equation and Wave Equation notebooks, where
the simulations are not running properly. The question
is, who can I contact to get support with this? I
would not want to bug you if this is not your job, but
I'm a little lost and got nobody to ask for help.</div>
