Detailed Description

Basic RBox database.

The function SetRBox() defines an array of predefined RBox structures needed to loop through different portions (or regions) of the computational domain.

  • rbox_center: an array of RBoxes for looping over the cell-centered data.
  • rbox_x1face: an array of RBoxes for looping over the X1-staggered data.
  • rbox_x2face: an array of RBoxes for looping over the X2-staggered data.
  • rbox_x3face: an array of RBoxes for looping over the X3-staggered data.

Each array of structures has 8 elements corresponding to the six sides of the computational domain (X1_BEG, ... , X3_END) and, in addition, we also define the DOM and TOT array indices to loop over the active computational zones or over the total computational domain (interior + ghost zones), respectively.

The function GetRBox() can be used to retrieve a pointer to a RBox structure given the computational side and the variable position.
