<tt>My point was that whatever your input is, the total energy on
the grid will depend on the problem parameters, including the mesh
resolution. Here is the total energy as the function of
lrefine_max for the Sedov problem with sim_expEnergy=1. So then
the first step is to establish the mesh resolution needed to
resolve the initial conditions.<br>

The actual initial value of the total will vary as one
changes problem parameters.<br>

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>
