bndPriorityOne [INTEGER] [1]
Valid Values: 1, 2, 3
indicates which 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)
(center,left,left),(center,left,right),
(center,right,left),(center,right,right),

(right,left,right),(right,center,left),
(right,center,right),(right,right,left),
(right,right,center),(right,right,right)
bndPriorityThree [INTEGER] [3]
Valid Values: 1, 2, 3
the least priority dimension in applying boundary conditions
bndPriorityTwo [INTEGER] [2]
Valid Values: 1, 2, 3
the second priority dimension in applying boundary conditions
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_recal_gather"]
Valid Values: "dens_ie", "dens_pres", "dens_temp", "dens_ie_all",
"dens_ie_scatter", "dens_ie_gather", "dens_ie_sele_gather",
"dens_temp_equi", "dens_temp_all", "dens_temp_gather",
"dens_ie_recal_gather", "dens_ie_mat_gather_pradscale"
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. Other values may also be available as, depending on
whether a multiTemp Eos is used and on implementation of additional
physics. For 3T simulations, the best choice is "dens_ie_recal_gather",
since this mode will ensure that total energy is conserved when
refinement changes occur.
eosModeInit [STRING] ["dens_ie"]
Valid Values: "dens_ie", "dens_pres", "dens_temp", "dens_ie_all",
"dens_ie_scatter", "dens_ie_gather", "dens_temp_equi", "dens_temp_all",
"dens_temp_gather", "eos_nop"
determines how to operate on thermodynamic quantities for the initial
conditions. A call to Simulation_initBlock sets initial conditions on
each block, and an eos call follows which ensures the initial values are
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.
Other values may also be available as, depending on whether a multiTemp
Eos is used and on implementation of additional physics.

whether to enable the Grid_bcApplyToRegionMixedGds interface for
implementing boundary conditions with access to the variables of mixed
GDSs (in particlular, cell-centered UNK varsiables and face variables).
This only has an effect if the GridBoundaryConditions subunit is
included and the simulation actually supplies an implementation of
Grid_bcApplyToRegionMixedGds.

Whether to use quadratic coarse-fine boundary interpolation.
convertToConsvdForMeshCalls [BOOLEAN] [TRUE]
indicates if appropriate variables are converted from primitive to
conserved form during propagation before control is passed to Chombo for
refinement, derefinement, or guardcell filling.
convertToConsvdInMeshInterp [BOOLEAN] [FALSE]
indicates if appropriate variables are converted to conserved form
during propagation within the interpolation routines invoked by Chombo.
This applies to interpolation (both "prolongation" and "restriction") in
the course of refinement, derefinement, or guardcell filling. This is
not yet implemented, but needs to get implemented soon because manually
converting in several different FLASH Fortran Grid leads to the
possibility of overlooking at least one FLASH Fortran Grid subroutine.

earlyBlockDistAdjustment [BOOLEAN] [TRUE]
If true, let Paramesh redistribute blocks across processors early, so
that the block distribution chosen by Paramesh will be in effect when
time evolution begins after restart. If earlyBlockDistAdjustment is
false, the block distribution enacted by the IO unit when it read a
checkpoint file will normally still be in effect when time evolution
begins after a restart. This flag is ignored if not restarting from a
checkpoint.

gr_lrefineMaxByTime [BOOLEAN] [FALSE]
This parameter activates the ability to manually specify values for

N is a number from 1 to 20) tell FLASH the times at which lrefine_max
changes will occur. The analogous parameters gr_lrefmaxTimeValue_N
(where N is a number from 1 to 20) tell FLASH the value of lrefine_max
to use at time gr_lrefmaxTime_N. For example, specifying the following
lines in your flash.par file tells FLASH to use an lrefine_max value of
10 at t = 1.0e-09 s and a value of 11 at t = 2.0e-09 s:
gr_lrefmaxTime_1 = 1.0e-09 gr_lrefmaxTimeValue_1 = 10 gr_lrefmaxTime_2 =

meaningful data. Data restrictions that happen as part of guard cell
filling or within multigrid solvers are not affected by this setting.
For PARAMESH 2, this runtime parameter is currently ignored. With

If > 0.0, directly sets a_tol (absolute tolerance) for the HYPRE
iterative solver. Convergence criteria: <= max( a_tol^2,
r_tol^2 * ). Note: default for a_tol is 0.0, so relative
residual criteria is used unless user specifies a_tol, or sets r_tol =
0.0, which means absolute tol only is checked. See also

Currently only used when gr_hypreSolverType is "HYPRE_PCG".

gr_hypreSolverAutoAbsTolFact [REAL] [0.0]
Valid Values: Unconstrained
If not 0.0, automatically set a_tol (absolute tolerance) for the HYPRE
iterative solver. If also gr_hypreAbsTol > 0, then the maximum of
gr_hypreAbsTol and the automatically determined value is taken. See
description of gr_hypreAbsTol for the use if a_tool in the HYPRE solver.
If gr_hypreSolverAutoAbsTolFact > 0, then set f =
gr_hypreSolverAutoAbsTolFact. If gr_hypreSolverAutoAbsTolFact < 0, then
set f = |gr_hypreSolverAutoAbsTolFact|*gr_hypreRelTol. In either case,
the automatically determined value for a_tol is
f*sqrt(). Here is a rough
estimate of the smallest possible value of the inverse of the diagonal
part of the matrix C representing the preconditioner. In that estimate,
bfloor is a vector that represents a worst-case tolerable error in b
(the RHS of the equation to be solved, A*x=b). Currently, bfloor is set
to a vector whose every element is set to gr_hypreFloor. If
gr_hypreAbsTol > 0 in addition to gr_hypreSolverAutoAbsTolFact .ne. 0.0,

geometry domains, even if this holds only approximately. In effect it
uses only M=0 multipole moments.
mpole_DumpMoments [BOOLEAN] [false]
Should the Moment array be dumped at each timestep? Use this option only
with care, as the moments will be printed for each radial bin.

Valid Values: 0.0 to INFTY
The resolution spacing for the inner zone in units of the inner zone
atomic radius. Two inner zone radii will be considered different if they
are more than the resolution spacing apart. A very tiny number will
result in a complete separation of all inner zone radii into separate
bins. However, the resolution cannot be set to exactly zero, because its
inverse value needs to be calculated at some point in the code.
