Detailed Description

template<int DIM>
class SAMRAI::appu::CutCell< DIM >

The CutCell struct holds data and methods to define a cut-cell on an irregular boundary.

Information maintained by the struct includes the following:

• INDEX - index (i,j,k) of the cell
• VOL FRACTION - volume fraction of the cell
• AREA FRACTION[2*DIM] - areas of the faces of the cell
• NORMAL[DIM] - normal to the cut plane through the cell
• FRONT AREA - area of exposed plane cutting the cell
• SURROUNDING VOL - volume of cells surrounding the cut cell
• NEW BASE - a basis aligned with the cell cut face
• BOUNDARY NODE[DIM**2] - nodes on the corners of the cut cell, which contain information for immersed boundary calculations

The copySourceItem() method allows CutCell to be a templated data type for IndexData - i.e. IndexData<DIM,CutCell<DIM>>. In addition to this method, the other methods that must be defined are getDataStreamSize(), packStream(), unpackStream() for communication, putToDatabase(), getFromDatabase for restart. These are described below.

template<int DIM>

size_t SAMRAI::appu::CutCell< DIM >::getDataStreamSize

(

)

The following functions enable parallel communication with CutCells. They are used in SAMRAI communication infrastructure to specify the number of bytes of data stored in each CutCell object, and to pack and unpack the data to the specified stream.

(

tbox::AbstractStream &

stream
