* @class vtkPExodusIIWriter
|
|
* @brief Write Exodus II files
|
|
*
|
|
* This is a vtkWriter that writes it's vtkUnstructuredGrid
|
|
* input out to an Exodus II file. Go to http://endo.sandia.gov/SEACAS/
|
|
* for more information about the Exodus II format.
|
|
*
|
|
* Exodus files contain much information that is not captured
|
|
* in a vtkUnstructuredGrid, such as time steps, information
|
|
* lines, node sets, and side sets. This information can be
|
|
* stored in a vtkModelMetadata object.
|
|
*
|
|
* The vtkExodusReader and vtkPExodusReader can create
|
|
* a vtkModelMetadata object and embed it in a vtkUnstructuredGrid
|
|
* in a series of field arrays. This writer searches for these
|
|
* field arrays and will use the metadata contained in them
|
|
* when creating the new Exodus II file.
|
|
*
|
|
* You can also explicitly give the vtkExodusIIWriter a
|
|
* vtkModelMetadata object to use when writing the file.
|
|
*
|
|
* In the absence of the information provided by vtkModelMetadata,
|
|
* if this writer is not part of a parallel application, we will use
|
|
* reasonable defaults for all the values in the output Exodus file.
|
|
* If you don't provide a block ID element array, we'll create a
|
|
* block for each cell type that appears in the unstructured grid.
|
|
*
|
|
* However if this writer is part of a parallel application (hence
|
|
* writing out a distributed Exodus file), then we need at the very
|
|
* least a list of all the block IDs that appear in the file. And
|
|
* we need the element array of block IDs for the input unstructured grid.
|
|
*
|
|
* In the absence of a vtkModelMetadata object, you can also provide
|
|
* time step information which we will include in the output Exodus
|
|
* file.
|
|
*
|
|
* @warning
|
|
* If the input floating point field arrays and point locations are all
|
|
* floats or all doubles, this class will operate more efficiently.
|
|
* Mixing floats and doubles will slow you down, because Exodus II
|
|
* requires that we write only floats or only doubles.
|
|
*
|
|
* @warning
|
|
* We use the terms "point" and "node" interchangeably.
|
|
* Also, we use the terms "element" and "cell" interchangeably.
