Driver/DriverMain
dr_abortPause [INTEGER] [2]
Valid Values: 0 to INFTY
When Driver_abortFlash is called to abnormally end execution, and
dr_abortPause is grater than zero, the FLASH Driver_abortFlash code will
sleep for dr_abortPause seconds after writing explanatory messages (to
standard output and, possibly, to log files) but before calling
MPI_ABORT. See also eachProcWritesOwnAbortLog for controlling the
generation of per-processor log files.
dtinit [REAL] [1.E-10]
Valid Values: Unconstrained
Initial timestep
dtmax [REAL] [1.E5]
Valid Values: Unconstrained

eachProcWritesOwnAbortLog [BOOLEAN] [FALSE]
Should each process writes messages to its own log file when
Driver_abortFlash gets called to abnormally end execution? If true, each
process in which Driver_abortFlash is called will attempt to write an
explanatory message to its own log file, whether that file already
existed or needs to be newly created. If false, the Driver_abortFlash
message will appear only in the regular log file (if the Logfile code
unit is used), and normally only when Driver_abortFlash is called by the
process with PE 0.

Grid/GridMain
bndPriorityOne [INTEGER] [1]
Valid Values: 1, 2, 3
indicates the direction (IAXIS, JAXIS or KAXIS) gets top priority when
applying boundary conditions in corner guardcells We define three values
for edges left, center, right, of which center represents interior,
while left and right represent the corresponding guardcells. We define a
corner where more than one dimension has its its guardcells, so the
application must determine which direction gets to fill them. In 2-D,
there are four corners: (left,left), (left,right), (right,left) and
(right,right). In 3-D case, the following corners are possible :
(left,left,left),(left,left,center),
(left,left,right),(left,center,left),
(left,center,right),(left,right,left),
(left,right,center),(left,right,right)

convertToConsvdForMeshCalls [BOOLEAN] [FALSE]
indicates if appropriate variables are converted from primitive to
conserved form during propagation before control is passed to Paramesh
for refinement, derefinement, or guardcell filling. This is the old way
of ensuring that solution variables are in the correct form for
interpolation. It involves unnecessary conversions back and forth and
should be obsoleted by the newer mechanism enabled by runtime parameter
"convertToConsvdInMeshInterp". The name is a replacement for the old
"conserved_var" which many people have found to be very confusing
terminology.
eosMode [STRING] ["dens_ie"]
Valid Values: "dens_ie", "dens_pres", "dens_temp"
determines how to operate on thermodynamic quantities Possible values
are "dens_ie", where density and internal energy are supplied and
pressure and temperature are returned; "dens_pres", where density and
pressure are given and energy and temperature are computed; and
"dens_temp", where density and temperature are given and pressure and
energy are computed. In future other values may become available as
relativistic physics is implemented in the code
eosModeInit [STRING] ["dens_ie"]
Valid Values: "dens_ie", "dens_pres", "dens_temp"

thermodynamically consistent. The value of eosModeInit determines the
mode in which these eos calls operate. Possible values are "dens_ie",
where density and internal energy are supplied and pressure and
temperature are returned; "dens_pres", where density and pressure are
given and energy and temperature are computed; and "dens_temp", where
density and temperature are given and pressure and energy are computed.

implemented in the code

convertToConsvdInMeshInterp [BOOLEAN] [TRUE]
indicates if appropriate variables are converted to conserved form
during propagation within the interpolation routines invoked by
Paramesh. This applies to interpolation (both "prolongation" and
"restriction") in the course of refinement, derefinement, or guardcell
filling. This is the newer way of ensuring that solution variables are
interpolated in the correct form. It avoids unnecessary conversions back
and force and should replace the old mechanism enabled by runtime
parameter "convertToConsvdForMeshCalls". However, it is only available
with PARAMESH 3 or later.

hy_fluxRepresentation [STRING] ["fluxes"]
Valid Values: "hybrid", "fluxes", "auto"
determines the nature of the data stored in flux arrays. With this
parameter set to "fluxes", the fluxes and cell volumes used in the Hydro
method are calculated correctly using geometry measures (in units
matching those in which coordinates are represented). If
hy_fluxRepresentation is "hybrid", fluxes are calculated in a simpler
way; for example, the fluxes in Cartesian coordinates use the convention
Face Area == 1 (and thus Cell Volume == dx during the X sweep, etc.).
Both settings lead to a correct algorithm, because what is ultimately
applied in the Hydro update is of the form fluxes times dt/CellVolume,
so cell areas (thus fluxes) and volumes can be multiplied by an
arbitrary constant (as long as it is done consistently) without changing
results (except for rounding effects). The setting here must match
Paramesh's understanding of what the "fluxes" are that it is being
passed if Grid_conserveFluxes is called: If hy_fluxRepresentation is
"fluxes", then Paramesh4 should have set consv_fluxes==.true.,
consv_flux_densities==.false. If hy_fluxRepresentation is "hybrid", then
Paramesh4 should have set consv_fluxes==.false.,
consv_flux_densities==.true. Hydro_init will try to set Paramesh to the
right mode if possible, this requires Paramesh to be compiled in LIBRARY
mode. If this fails, the flux representation will be modified to
correspond to what the Grid unit supports. A third possible value for
hy_fluxRepresentation is "auto", in which case the Hydro code unit will
pick either "fluxes" or "hybrid" based on geometry and support in Grid.
