NAME: GridFV - finite volume grid
DESCRIPTION:
The class "GridFV" offers a grid representation tailored for finite volume calculations. This grid class is capable of handling a fully unstructured mesh with a mix of different volume types.
|
|
The "GridFV" object needs to be initialized from a preprocessor, or from an existing "GridFE" object. One of the constructors accepts a "GridFE" object as input and will use the class "GridFE2GridFV" to convert the element grid to a finite colume grid. There is also a collection of member functions that assist in the construction of a "GridFV" object, typically intended for use by preprocessors. Moreover, valid data files in "GridFV" format can be read by the "scan" functions. |
|
|
See documentation of one of the overloaded constructor. |

|
|
turns indicators on or off for a specified vertex. |
|
|
|
|
|
|
|
|
See documentation of one of the overloaded functions. |
|
|
adds a material type for a specified region. |
|
|
connects a "Indicators" object to the current grid. |
|
|
|
|
|
|
|
|
See documentation of one of the overloaded functions. |
|
|
See documentation of one of the overloaded functions. |
|
|
returns true if the specified face is subject to any or one specified boundary indicator. A face is subject to an indicator if all vertices of the face are subject to the indicator. The face can be specified directly or locally within a given control volume. |
|
|
See documentation of one of the overloaded functions. |
|
|
provides direct access to the "Indicators" object used for storage of boundary indicators. |
|
|
turns off a particular boundary indicator at a node ("OFF" mode). |
|
|
turns off all boundary indicators. |
|
|
|
|
|
estimates the total number of degrees of freedom in this "GridFV" object. There is supposed to be one degree of freedom for each volume and one for each boundary face in the grid. |
|
|
|
|
|
|
|
|
|
|
|
computes the total number of degrees of freedom, counting both volumes and boundary faces.This is only used by grid converters and preprocessors. |
|
|
|
|
|
|
|
|
based on the current grid, create the dual grid. The dual grid states are primary grid (triangulation) or secondary grid (polygonal volumes). A "GridFV" object generated from a finite element grid is automatically a secondary grid. This convention appears normal in that most non-trivial finite volume grids are constructed on basis of a triangulation, e.g. in terms of a Voronoi grid constructed on basis of a Delauney triangulation. |
|
|
|
|
|
|
|
|
returns the logical name of the specified boundary indicator. |
|
|
See documentation of one of the overloaded functions. |
|
|
See documentation of one of the overloaded functions. |
|
|
returns the coordinates of the centroid in the specified control volume. |
|
|
See documentation of one of the overloaded functions. |
|
|
See documentation of one of the overloaded functions. |
|
|
returns the coordinates of the specified degree of freedom. |
|
|
returns a pointer to the dual grid. If the dual grid is not present, e.g. by not having called "createDualGrid", a "NULL" pointer is returned. |
|
|
returns the area of the specified face. |
|
|
|
|
|
|
|
|
|
|
|
See documentation of one of the overloaded functions. |
|
|
returns the coordinates of the midpoint/centroid of the specified face. |
|
|
returns the unit normal vector positioned at the midpoint/centroid of the specified face. The optional second argument specifies which volume that is taken to be the basis for the normal vector. That is, the vector will point outwards from the face on the specified volume. Valid volume numbers refers to the two volumes sharing the face. The default value (of volume number 0) will make the vector point outwards from the first volume that defined the specified face. The result of this will depend on the algorithm used for the grid generation. |
|
|
|
|
|
returns the shape of the specified face. |
|
|
returns an array containing the coordinates of the vertices defining the specified face. Each row in the array refers to one vertex, and the columns refers to the individual components. |
|
|
returns a pointer to the finite element grid ("GridFE" object) which was the basis of the current finite volume grid. This function is only meaningful when a conversion from a "GridFE" object has taken place, e.g. by use of the "GridFE2GridFV" utility class. If such a finite element grid is not present, the functions returns a "NULL" pointer. |
|
|
returns the grid state as primary (triangulation) versus secondary (polygonal). See also the function "createDualGrid". |
|
|
returns the grid type describing the algorithm used for its construction. Although the return value is a "String", the possible values are defined by the "enum" data type "GridFVType". |

as "getVolShape", but returns the value as a "String" rather than a "FVShape". |
|
|

|
|
|
|
|
|
|

|
|
generate a map from local to global degree of freedom numbering for the specified internal volume. An internal volume is a control volume without boundary faces. |
|
|
|
|
|
a local variant of "GridWithPts nearestPoint"; it just calls that function. The reason to include "nearestPoint" as a member function, is that "GridWithPts" defines the function to be virtual, but provides no default version (a general static function requiring a coordinate array for the grid points is offered and it is this function that is called from "GridFV nearestPoint"). The function returns the node number that is closest to "point". The "distance" parameter reflects the distance between the nearest node/point and the "point". The "exact" variable is true at return if "point" is a node. Reimplemented from GridWithPts. |
|
|
See documentation of one of the overloaded functions. |
|
|
advances to the next degree of freedom in the grid. Reimplemented from GridWithPts. |

|
|
See documentation of one of the overloaded functions. |
|
|

|
|
inserts a new face as the specified local face of the given volume number. The supplied vertex numbers "from_vertex" and "to_vertex" will be the endpoints for the new face. The direction of the face should be as seen when making a counterclock traversal of faces for the volume "volno". Neighbor information is automatically updated. This is only used by grid converters and preprocessors. |
|
|
inserts the mapping of local to global vertex numbering for a specified control volume. This is only used by grid converters and preprocessors. |
|

insert the specified volume number in the list of volumes sharing the specified vertex node. If the connection has already been made, it is ignored. That is the resulting vertex to volume list will only have unique volume numbers. This is only used by grid converters and preprocessors. |
|
|
See documentation of one of the overloaded functions. |
|
|
inserts the coordinates of a specified vertex, either component by component or in terms of a "Ptv(real)" object. This is only used by grid converters and preprocessors. |

|
|
See documentation of one of the overloaded functions. |

|
|
|
|
|
redimensions the storage of degrees of freedom. This function requires "redimVertexData" and "rediumFaceAndNeighborData" to be called first. |
|
|
redimensions the table for face to vertex neighbor information. The number of rows corresponds to the number of faces in the grid, whereas the number of columns refers to the maximum number of vertices in any face in the grid. An extra column (the last one) is used to store the actual number of vertices used for a given volume. This is only used by grid converters and preprocessors. |
|
|
See documentation of one of the overloaded functions. |
|
|
redimensions the storage needed for the faces between volumes and for the grid topology (neighbor data). This function takes a "GridFVSIzeInfo" object as input. This function requires "redimVertexData" to be called first. |

sets the current grid state as either "PRIMARY_GRIDFV" (triangular, or FEM-like, grid)or "SECONDARY_GRIDFV" (polygonal grid). |
|
|
See documentation of one of the overloaded functions. |
|
|
sets the current grid type, indicating how the grid was created. |
|
|
assigns material type "material_number" to control volume "volno". This information is not used by the Diffpack libraries, but can be used at the application level, e.g. to set material dependent properties. |
|
|
|
|
|
|
|
|
|
|
|
defines the number of vertices that are in use for a given control volume. This is only used by grid converters and preprocessors. |
|

|
|
updates face information in a "GridFVSizeInfo" object and prepares the current grid object for insertion of face information. This is only used by grid converters and preprocessors. |
