<p>Malia,</p>

<p>Could you maybe provide the log file from your simulation? And
generally more other information.<br>
</p>
<p><br>
</p>
<p>I have a super hard time understanding how your second snapshot
could only be one step after your first. In one timestep, flow
can only propagate from one cell to its immediate neighbors. But
your second snapshot shows what appear to be coherent large-scale
flow structures compared to your first. It seems impossible for
this to happen in one timestep.</p>
<p><br>
</p>
<p>Depending on what you have done for gravity and temperature, your
second snapshot seems to me like a fairly reasonable progression
from your first, but I would have said it would take no less than
100 timesteps to develop this type of flow. The central density
peak expands explosively and interacts with the other material
further out along the equatorial plane. More information about
what you are trying to do would help in interpreting this.</p>

<p>I am making a plot file every time step and these are what I
get from step 0 to 1. I think it might be an issue of breaking
the Courant conditions. I am planning to try reducing the time
step to solve the issue. The run is in cylindrical coordinates
with open boundaries on Z and the outside of R. The inside
(r=0) boundary is a reflection boundary. I wanted to see if
there were any other ideas of how to correct the large jump
between these steps.</p>
