Detailed Description

A wrapper for an FArrayBox to contain NODE-centered data.

This is a class to contain NODE-centered data on a box.
Question: Why not just use NODE-centered FArrayBox?
Answer: We want to use LevelData<NodeFArrayBox>, which requires that the underlying BoxLayout be a DisjointBoxLayout. Adjacent NODE-centered boxes intersect, but adjacent CELL-centered boxes do not.
The underlying DisjointBoxLayout will be CELL-centered.

In a LevelData<NodeFArrayBox>, some of the grids may share nodes. The data on shared nodes must be the same.

Example: A four-grid layout is shown on the left. As shown on the right, the nodes marked "2" are shared by two grids, and those marked "3" are shared by three grids.

:                                   :                                   :
:                +-----+            :                YYYY--+            :

:        |    D     |               :        |    D     |               :
:        |          |               :        |          |               :
:        +----------+               :        +-------YYYY               :
:                                   :                                   :
    
Additional nodes may be shared if the boxes extend to the faces of a domain that is periodic in one or more directions. In the example above, these nodes are marked "X" and "Y".
Horizontally periodic domain: node "X" shared by two grids, C and D.
Vertically periodic domain: nodes "Y" shared by two grids, A and D.

Using copyTo:

One of the most useful features of LevelData<NodeFArrayBox> is the copyTo() function. THE copyTo() FUNCTION MUST BE USED WITH CAUTION if the source and destination have different layouts.

Consider an example where A and B are on layouts of one box each, and these two boxes abut:

    +-------+
    |       |
    |   A   |
    |       |
    =========
    |       |
    |   B   |
    |       |
    +-------+
    
If we do A.copyTo(B), then the data on the nodes of the interface (marked "=") are NOT copied, because the underlying CELL-centered DisjointBoxLayouts of the LevelDatas do not intersect.

In general, doing src.copyTo(dest): if LevelData<NodeFArrayBox> src and LevelData<NodeFArrayBox> dest do NOT have identical underlying boxes in their layouts, then src.copyTo(dest) will NOT copy the interface nodes.

Here are two different ways to make sure the interface nodes are copied:

1. Do copyTo to a BoxLayoutData<NodeFArrayBox> defined on the BoxLayout of dest with each box expanded by 1 in each dimension. That is:

    BoxLayout destExpandedLayout;
    destExpandedLayout.deepCopy(dest.disjointBoxLayout());
    destExpandedLayout.grow(1);
    destExpandedLayout.closeNoSort();
    src.copyTo(destExpanded);
    for (DataIterator dit = dest.dataIterator(); dit.ok(); ++dit)
      {
        dest[dit].copy(destExpanded[dit]);
      }

2. Define src with ghost vector IntVect::Unit, and in copyTo, use a Copier with ghost vector IntVect::Unit. That is:

    Copier myCopier;
    myCopier.ghostDefine(src.disjointBoxLayout(),
                         dest.disjointBoxLayout(),
                         src.disjointBoxLayout().physDomain(),
                         IntVect::Unit);
    src.copyTo(dest, myCopier);
For this to work, src must have been defined with ghost vector IntVect::Unit (at least).

void NodeFArrayBox::copy ( const NodeFArrayBox a_src  ) 

Modifies the data in this NodeFArrayBox by copying data from a_src into it, over the nodes that they have in common.
If this NodeFArrayBox and a_src have abutting grids, as shown:

      +--------+
      |        |
      |  this  |
      |        |
      ==========   <- data copied here from a_src to this
      |        |
      |  a_src |
      |        |
      +--------+
      
then the data in this NodeFArrayBox WILL be modified along the edge nodes where they abut -- even though this.box() and a_src.box(), being CELL-centered, do NOT intersect.

All components are copied.

void NodeFArrayBox::copy ( const Box a_regionFrom,
const Interval a_Cdest,
const Box a_regionTo,
const NodeFArrayBox a_src,
const Interval a_Csrc 
)

Modifies the data in this NodeFArrayBox by copying the data from a_src into it, over the intersection of:

  • the nodes surrounding the CELL-centered box a_regionFrom;
  • the nodes surrounding the CELL-centered box a_regionTo;
  • the nodes containing data in this NodeFArrayBox;
  • the nodes containing data in a_src.

The components in the interval a_Csrc in a_src are copied to the components in the interval a_Cdest in this NodeFArrayBox.

This function is required in order to have BoxLayoutData<NodeFArrayBox>.

size_t NodeFArrayBox::size ( const Box a_R,
const Interval a_comps 
) const

const Box a_R,

void NodeFArrayBox::setVal ( Real  a_x  ) 

Modifies this NodeFArrayBox so that all values of all components are set to the given value, a_x. (FArrayBox inherits such a function from BaseFab.)

void NodeFArrayBox::setVal ( Real  a_x,
const Box a_bx,
int  a_nstart,
int  a_numcomp 
)

The setVal functions set subregions in the `BaseFab' to a constant value. This most general form specifies the subbox, the starting component number, and the number of components to be set.
