Detailed Description

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

This class provides an interface to the Cubes geometry library, the embedded boundary grid generator in the Cart3D package from NASA Ames (http://people.nas.nasa.gov/~aftosmis/cart3d/).

Use of this class first requires that you link with the Cubes library. The package may be obtained by filling out a license agreement at the website listed above. Next, you must specify a 'CubesPatchInterface {...}" input entry in the input for the EmbeddedBoundaryGeometry class. In this input you specify the name of the triangulated surface grid file that defines the surface geometry.

Once an instance of the class is created, SAMRAI will pass patch information to the "calculateCutCellInfo()" class whenever an embedded boundary is constructed on a new level. Cubes computes the list of cut cells on the patch and stores them as IndexData, templated on the CutCell class.

Required input keys and data types:

• surface_tri_file
  string indicating the name of the triangulated surface file that defines the surface geometry.
• max_levels int value indicating the maximum number of levels used to construct the ADT tree in Cubes. In general, this should be equal to the maximum number of levels in the hierarchy. Because it is mainly used for storage, it may be larger, but should never be smaller than the number of hierarchy levels.

Optional input keys:

• verbose
  boolean turns on the 'verbose' flag in cubes.

A sample input file entry might look like:

* 
*   CubesPatchInterface {
*      surface_tri_file = "slc-rev.tri"
*      max_levels       = 5
*      verbose          = TRUE
*   }
*
*

Constructor & Destructor Documentation

CubesPatchInterface()

template<int DIM>

SAMRAI::appu::CubesPatchInterface< DIM >::CubesPatchInterface	(	const std::string &	object_name,
		tbox::Pointer< tbox::Database >	input_db,
		tbox::Pointer< geom::CartesianGridGeometry< DIM > >	grid_geom,
		hier::IntVector< DIM >	nghosts
	)

The constructor initializes the Cubes library and optionally starts an interactive interface

Parameters

object_name	name of object of this class
input_db	the input database which contains the name of the surface geometry.
grid_geom	grid geometry
nghosts	number of ghost cells

~CubesPatchInterface()

template<int DIM>

virtual SAMRAI::appu::CubesPatchInterface< DIM >::~CubesPatchInterface ( )

virtual

The destructor does nothing.

Member Function Documentation

calculateCutCellInfo()

template<int DIM>

void SAMRAI::appu::CubesPatchInterface< DIM >::calculateCutCellInfo	(	tbox::Pointer< hier::Patch< DIM > > &	patch,
		const int	cell_flag_data_id,
		const int	cell_vol_data_id,
		const int	cutcell_data_id
	)

Compute set of cut cells on a patch. This method makes calls to the cubes library, passing in the patch extents, and returning the set of cut cells on the patch.

Parameters

patch	pointer to a patch on a hierarchy level
cell_flag_data_id	descriptor id for integer array holding cell flag. Stored on every cell of the patch, designates cell as flow, solid, or cut.
cell_vol_data_id	descriptor id for double array holding volume fraction. Stored on every cell of the patch.
cutcell_data_id	descriptor id for IndexData<CutCell> data.

setRecordAreasAndNormal()

template<int DIM>

void SAMRAI::appu::CubesPatchInterface< DIM >::setRecordAreasAndNormal

(

const bool

record_an

)

Set whether to record areas and normal. Some calculations do not require this information. By default, it is set TRUE.

printClassData()

template<int DIM>

virtual void SAMRAI::appu::CubesPatchInterface< DIM >::printClassData ( std::ostream &  os ) const

virtual

Dump data to supplied stream.

getFromInput()

template<int DIM>

void SAMRAI::appu::CubesPatchInterface< DIM >::getFromInput
