NAME: GridPart - abstract base class of a method hierarchy for preparing subgrids to be used in parallel computing
DESCRIPTION:
This abstract base class gives a generic interface of methods that can be used to prepare subgrids for doing parallel computing in Diffpack. Different subclasses are already developed to handle different situations (see "GridPartFileSource", "GridPartUnstruct", and "GridPartUniform"). The user normally does not work directly with "GridPart". Instead, class "GridPartAdm" takes care of instantiating an object of a subclass of "GridPart" and invoking one relevant member function from it to prepare the subgrids.
|
|
There is only one constructor that takes an input "GridPart_prm" object and binds the internal "Handle(GridPart_prm)" to it. The information contained in "GridPart_prm" will be used extensively in later operations. |
|
|
|
|
|
returns all the subgrids (one or multiple) located on one processor. |
|
|
returns a "VecSimplest" of "VecSimple(int)" containing global element numbering for all the elements in all the subgrids on one processor. |
|
|
returns a "VecSimplest" of "VecSimple(int)" containing global node numbering for all the nodes of all the subgrids on one processor. |
|
|
returns the desired subgrid. The optional integer input is the local number of the subgrid when there exist multiple subgrids on the current processor. This function is normally invoked by "GridPartAdm" through its own member function with the same name. |
|
|
is a function for calculating e2e information. It is a lightweight version of the "NeighborFE init" function. The result is returned in an integer matrix, where each row contains neighbor information for a particular element on each of its sides. A positive number gives the neighbor element index, while 0 means there is no neighbor. This member function is static so it can be used outside the "GridPart" hierarchy. |
|
|
See documentation of one of the overloaded functions. Reimplemented in GridPartFileSource, GridPartUniform, and GridPartUnstruct. |
|
|
has two versions, one takes an object of "GridFE" as input, the other has no input parameter. Some of the subclasses of "GridPart" support only one version. This function is normally invoked by "GridPartAdm", and information contained in the "GridPart_prm" object will be used extensively during the preparation of subgrids. Reimplemented in GridPartFileSource, GridPartUniform, and GridPartUnstruct. |
