Problem Definition

The following inputs must be preceded by “amr.”

	Description	Type	Default
n_cell	Number of cells at level 0 in each coordinate direction	Int Int Int	None
max_level	Maximum level of refinement allowed (0 when single-level)	Int	None

The following inputs must be preceded by “geometry.”

	Description	Type	Default
coord_sys	0 for Cartesian	Int	0
is_periodic	1 for true, 0 for false (one value for each coordinate direction)	Ints	0 0 0
prob_lo	Low corner of physical domain (physical not index space)	Reals	0 0 0
prob_hi	High corner of physical domain (physical not index space)	Reals	None
prob_extent	Extent of physical domain (physical not index space)	Reals	None

Note that internally prob_lo and prob_hi are the variables carried by the Geometry class. In the inputs file (or command line), one can specify 1) geometry.prob_hi only or 2) geometry.prob_extent only or 3) geometry.prob_lo and geometry.prob_hi or 4) geometry.prob_lo and geometry.prob_extent. If geometry.prob_lo is not specified then it will be 0 in each coordinate direction. If geometry.prob_extent is specified (and geometry.prob_hi is not) then internally “prob_hi” will be set to “prob_lo” + “prob_extent”.
