Within our code, the problem domain's data is held in {{{InfoDef}}} structures, which is why so many module subroutines take an {{{InfoDef}}} structure as a parameter.

+All AstroBEAR modules have at least one thing in common: initializing the problem domain.  Within our code, the problem domain's data is held in {{{InfoDef}}} structures, which is why so many module subroutines take an {{{InfoDef}}} structure as a parameter.
 
 There are two major data arrays in {{{InfoDef}}}: the {{{q}}} array and the {{{aux}}} array.  {{{q}}} holds the cell-centered data and is used by all AstroBEAR simulations.  The {{{q}}} array takes the form {{{q(x,y,z,variable)}}} where {{{variable}}} is itself a 1D array that holds the physical quantities such as density, momentum, energy, etc. The order of the quantities in the {{{variable}}} array is {{{(rho, px, py, pz, E)}}}. The {{{aux}}} array holds face-centered data, and is only used in MHD problems.  If you are running a strictly hydrodynamic problem or a hydrodynamic + elliptic problem, then you will not need {{{aux}}}.
