Detailed Description

Reader for IOSS (Sierra IO System)

vtkIOSSReader is reader that uses the IOSS (Sierra IO System) library to read files. Currently, this reader support Exodus and CGNS file formats. IOSS imposes certain restrictions on these file formats and hence it may not be possible to open every Exodus or CGNS file using this reader. This is true especially for CGNS, more so than Exodus. In that case vtkCGNSReader may be more appropriate.

Specifying Files

One can select a single file to read using vtkIOSSReader::SetFileName. With IOSS, however, it is not uncommon to have a collection of files named using standard patterns (described in Section IOSS Naming Conventions). To support this use-case, the reader automatically scans for additionally files internally. To disable this behaviour, call vtkIOSSReader::ScanForRelatedFilesOff.

Alternatively, the list of files to be read can be explicitly specified using vtkIOSSReader::AddFileName. Then too, if ScanForRelatedFiles is true, the reader will search for related files for each of the files specified.

Additionally, FileRange and FileStride may be used to limit to reading a subset of files.

Selecting blocks and sets to read

An IOSS file comprises of blocks and sets of various types. These are described by the enum vtkIOSSReader::EntityType.

vtkIOSSReader::GetEntitySelection returns a vtkDataArraySelection instance for each of the entity types. This vtkDataArraySelection can be used to query the names for available blocks or sets and also select which ones to read.

Typical usage is as follows:

vtkNew<vtkIOSSReader> reader;
reader->SetFileName(...);
reader->UpdateInformation();
reader->GetElementBlockSelection()->EnableArray("Block0");
reader->GetEntitySelection(vtkIOSSReader::SIDESET)->DisableAllArrays();

By default, all blocks are enabled, while all sets are disabled.

In additional to selecting blocks and sets by name, if the file defines assemblies that organize these blocks and sets, then one can use selector expressions to enable blocks/sets as defined in the assemblies.

A block (or set) is treated as enabled if it is either explicitly enabled using the block selection or implicitly enabled due to a selector specified on over the assemblies.

Typical usage to select blocks by assembly alone is as follows:

vtkNew<vtkIOSSReader> reader;
reader->SetFileName(...);
reader->UpdateInformation();
reader->GetElementBlockSelection()->DisableAllArrays();
...
reader->AddSelector("//Low");
reader->AddSelector("//High");

Selecting arrays to read

Similar to the block and set selection, arrays (or fields as IOSS refers to them) to read from each of the blocks or sets can be specified using the vtkDataArraySelection instance returned using vtkIOSSReader::GetFieldSelection (or one of its convenience variants).

By default all arrays are enabled.

IOSS Naming Conventions

An IOSS complete dataset is referred to as a database. There can be multiple multiple timesteps in a single database. A single database may split among multiple files. When a database is split among multiple files, this is strictly spatial partitioning with each file storing part of the data for a specific partition. In this case, the files are named with suffix .{NP}.{RANK} where {NP} is the total number of partitions and {RANK} is the partition number. For example, if database named can.e is split among four files representing 4 partitions, it will be named as follows:

*  can.e.4.0
*  can.e.4.1
*  can.e.4.2
*  can.e.4.3
*

In this example, the database name is can.e while the .4.[0-4] suffix provides the partition information.

Note, the database need not be split into multiple files. Thus, a writer may generate a single can.e file that has all the timesteps and paritions and still provide all information available when the database is split among multiple files.

Multiple databases (with each stored in a single file or spatially split among files) can form a temporal sequence. This done by using another file naming convention. If the database name is followed by -s.{RS}, where {RS} is some number sequence), then the databases are treated as a temporal sequence with {RS} (called restart numbers) representing the temporal sequence order.

The follow represents a temporal sequence:

*  mysimoutput.e-s.000
*  mysimoutput.e-s.001
*  mysimoutput.e-s.002
*

You can use any number of digits for the restart number, but by convention the number used should be the same for all files. Also by convention, you can leave off the -s.{RS} suffix for the first file. The following sequence is internally the same as that above:

*  mysimoutput.e-s
*  mysimoutput.e-s.001
*  mysimoutput.e-s.002
*

When a database in the temporal sequence is spatially split in multiple files, the corresponding filename is suffixed by the partition information. For example:

*  mysimoutput.e-s.2.0
*  mysimoutput.e-s.2.1
*  mysimoutput.e-s.001.2.0
*  mysimoutput.e-s.001.2.1
*  mysimoutput.e-s.002.2.0
*  mysimoutput.e-s.002.2.1
*

In this case, the filenames take the form {DBNAME}-s.{RS}.{NP}.{RANK}, where {DBNAME} is the database name, {RS} is the restart number, {NP} is the number of spatial partitions and {RANK} is the spatial partition number.

This provides a mechanism to limit to reading to certain files in a spatially partitioned file-series.

To just specific subset of files, one can always simply specify those files using AddFileName and then set ScanForRelatedFiles to false. Another way is to let the reader scan for all related files and then use FileRange and FileStride to limit which files are read.
