<tt>The relevant data is the total energy shown in the first line of
the dat file. That should stay constant with relative accuracy
better than 1e-10.<br>
<br>
The actual initial value of the total will vary as one changes
problem parameters.<br>

style="font-family:arial,helvetica,sans-serif">I've been
running supernova remnant evolution simulations. The
initialization is done with code taken from the supplied Sedov
simulation with certain small changes. One issue that I've
run into is that the total energy is not very accurate. That
is, though the energy is conserved, the total energy,
initially input as thermal energy, is below that which is
given in the sim_expEnergy parameter by ~5%. Has anyone else
run into this? I don't think that it has to do with any of
the changes that I've made to Simulation_initBlock or
Simulation_init. I'm wondering if increasing the
sim_nsubzones parameter might help. Any advice would be
appreciated.</div>
