    5454==== Simulation Data ====

    56 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.  To make use of the {{{InfoDef}}} structure you will need to have the statement {{{USE DataDeclarations}}} at the beginning of {{{problem.f90}}}.

    5861There 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 {{{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}}}.
