Parameters:
filenames (`pathlib.Path`, `str` or `list`): CONVERGE HDF5 data files to be
read. (See note below concerning absolute and relative paths.)
frame (`Frame <tecplot.layout.Frame>`, optional): The `Frame
<tecplot.layout.Frame>` to attach the resulting `Dataset`. If
`None`, the currently active `Frame <tecplot.layout.Frame>` is used

read_data_option (`ReadDataOption`, optional): Specify how the data

Possible values are:
* `ReadDataOption.ReplaceInActiveFrame`
Remove the dataset from the active frame prior to reading in the
new dataset. If other frames use the same `Dataset
<tecplot.data.Dataset>` in the active frame, they will continue to
use the old one.
* `ReadDataOption.Append`
Append to the existing `Dataset <tecplot.data.Dataset>`.
* `ReadDataOption.Replace`
Replace the `Dataset <tecplot.data.Dataset>` attached to the active
frame and to all other frames that use the same `Dataset
<tecplot.data.Dataset>`.
reset_style (`bool`, optional): Reset the style for
destination `Frame <layout.Frame>`. If `False`, the `Frame
<layout.Frame>`'s current style is preserved. (default: `True`)
initial_plot_type (`PlotType`, optional): Forces a specific type of
plot upon loading of the data. Only used if *resetstyle* is `True`.
To have |Tecplot 360| determine the most appropriate plot type
for the data, use `PlotType.Automatic`. Possible values are:
`PlotType.Automatic` (default), `Cartesian3D`, `Cartesian2D`,
`XYLine`, `PlotType.Sketch`, `PolarLine`.
Returns:

"""Read Fluent Common Fluids Format files.
Parameters:
filenames (`pathlib.Path`, `str` or `list`): One or more Fluent CFF
case (*.cas.h5*) files followed by zero or more Fluent CFF data
(*.dat.h5*) files (See note below concerning absolute and relative
paths.)
frame (`Frame <tecplot.layout.Frame>`, optional): The `Frame
<tecplot.layout.Frame>` to attach the resulting `Dataset`. If
`None`, the currently active `Frame <tecplot.layout.Frame>` is used
and the zones are appended by default.
read_data_option (`ReadDataOption`, optional): Specify how the data
is loaded into Tecplot. (default: `ReadDataOption.Append`)
Possible values are:
* `ReadDataOption.ReplaceInActiveFrame`
Remove the dataset from the active frame prior to reading in the
new dataset. If other frames use the same `Dataset
<tecplot.data.Dataset>` in the active frame, they will continue to
use the old one.
* `ReadDataOption.Append`
Append to the existing `Dataset <tecplot.data.Dataset>`.
* `ReadDataOption.Replace`
Replace the `Dataset <tecplot.data.Dataset>` attached to the active
frame and to all other frames that use the same `Dataset
<tecplot.data.Dataset>`.
reset_style (`bool`, optional): Reset the style for
destination `Frame <layout.Frame>`. If `False`, the `Frame
<layout.Frame>`'s current style is preserved. (default: `True`)
initial_plot_type (`PlotType`, optional): Forces a specific type of
plot upon loading of the data. Only used if *resetstyle* is `True`.
To have |Tecplot 360| determine the most appropriate plot type for
the data, use `PlotType.Automatic`. Possible values are:
`PlotType.Automatic`, `Cartesian3D`, `Cartesian2D`, `XYLine`,
`PlotType.Sketch`, `PolarLine`. (default: `PlotType.Automatic`)
solution_time_source (`FluentCFFLoader.SolutionTimeSource`, optional):
Assign the solution times of the zones based on the specified
criteria. (default: `FluentCFFLoader.SolutionTimeSource.Auto`)
Possible values are:
* `FluentCFFLoader.SolutionTimeSource.Auto`
First looks for and uses solution time specified in the
simulation settings of the Fluent CFF data files. If that
information isn't present in all supplied files, next looks
for solution time embedded in ``filenames``. If solution
time cannot be determined, the loader assigns a constant
time interval, starting at zero and incrementing by one, if
there is a single file, or if there are case and data file
combinations, otherwise assigns static solution times of
zero.
* `FluentCFFLoader.SolutionTimeSource.SteadyState`
Assigns a static solution time of zero to all zones.
* `FluentCFFLoader.SolutionTimeSource.ConstantTimeInterval`
Assigns a constant time interval, starting at zero and
incrementing by one
include_interior_face_zones (`bool`, optional): Interior face zones,
which are used to build cell zones, are loaded as independent
face zones. (default: `False`)
include_particle_zones (`bool`, optional): Loads particle data as
I-ordered zones and nodal variables if it exists in the data
(*dat.h5*) file(s). (default: `True`)
Returns:
`Dataset <tecplot.data.Dataset>`: The `Dataset <tecplot.data.Dataset>` holding
the loaded data.
.. note:: **Absolute and relative paths with PyTecplot**
Relative paths, when used within the PyTecplot API are always from
Python's current working directory which can be obtained by calling
:func:`os.getcwd()`. This is true for batch and `connected
<tecplot.session.connect()>` modes. One exception to this is paths
within a macro command or file which will be relative to the |Tecplot
Engine|'s home directory, which is typically the |Tecplot 360|
installation directory. Finally, when connected to a remote (non-local)
instance of Tecplot 360, only absolute paths are allowed.
Note that backslashes must be escaped which is especially important for
windows paths such as ``"C:\\\\Users"`` or ``"\\\\\\\\server\\\\path"``
which will resolve to ``"C:\\Users"`` and ``"\\\\server\\path"``
respectively. Alternatively, one may use Python's raw strings:
``r"C:\\Users"`` and ``r"\\\\server\\path"``

# specified as strings and **read_data_option** is set to
# `ReadDataOption.Append` then variables will be aligned with
# existing variables. If variable offsets are supplied then
# the variables at those offsets will be loaded.
# Use `None` to load all variables. (default: `None`)
"""Read tecplot SZL data file.
Parameters:
filenames (`pathlib.Path`, `str` or `list`): Files to be read. (See note below
concerning absolute and relative paths.)
frame (`Frame <tecplot.layout.Frame>`, optional): The `Frame
<tecplot.layout.Frame>` to attach the resulting `Dataset`. If
`None`, the currently active `Frame <tecplot.layout.Frame>` is used
and the zones are appended by default.
read_data_option (`ReadDataOption`, optional): Specify how the data
is loaded into Tecplot. (default: `ReadDataOption.Append`)
Possible values are:
* `ReadDataOption.ReplaceInActiveFrame`
Remove the dataset from the active frame prior to reading in the
new dataset. If other frames use the same `Dataset
<tecplot.data.Dataset>` in the active frame, they will continue to
use the old one.
* `ReadDataOption.Append`
Append to the existing `Dataset <tecplot.data.Dataset>`.
Note also that when appending, the variables in the incoming dataset
will be matched up with the existing variables by name and any new
variables will be added to the end of the list.
* `ReadDataOption.Replace`
Replace the `Dataset <tecplot.data.Dataset>` attached to the active
frame and to all other frames that use the same `Dataset
<tecplot.data.Dataset>`.
reset_style (`bool`, optional): Reset the style for
destination `Frame <layout.Frame>`. If `False`, the `Frame
<layout.Frame>`'s current style is preserved. (default: `True`)
initial_plot_first_zone_only (`bool`, optional): Informs
the |Tecplot Engine| that after the data is loaded it only needs to
activate the first enabled `Zone <data_access>` for the initial
plot. This option is particularly useful if you have many `Zones
<data_access>` and want to get the data into the |Tecplot Engine|
and the first `Zone <data_access>` drawn as fast as possible. The
inactive `Zones <data_access>` can always be activated when needed.
(default: `False`)
initial_plot_type (`PlotType`, optional): Forces a specific type of
plot upon loading of the data. Only used if *resetstyle* is `True`.
To have |Tecplot 360| determine the most appropriate plot type
for the data, use `PlotType.Automatic`. Possible values are:
`PlotType.Automatic` (default), `Cartesian3D`, `Cartesian2D`,
`XYLine`, `PlotType.Sketch`, `PolarLine`.
assign_strand_ids (`bool`, optional): Assign strand ID's to
zones that have a strand ID of -1. (default: `True`)
add_zones_to_existing_strands (`bool`, optional): Add the
`Zones <data_access>` to matching strands, if they exist. Otherwise, if the
new data specifies strands, new ones will be created beginning after the
last strand in the `Dataset <tecplot.data.Dataset>`. (default: `False`)
server (`str`, optional): Load the data remotely from this
server address. When provided, file paths will be relative to the
SZL server's working directory. (default: `None`)
connection_method (`SZLLoader.RemoteConnectionMethod`, optional): When
*server* is given, this specifies the type of connection to be
made. Possible values are:
`SZLLoader.RemoteConnectionMethod.Tunneled` (default),
`SZLLoader.RemoteConnectionMethod.Direct`,
`SZLLoader.RemoteConnectionMethod.Manual`.
user (`str`, optional): When *server* is given and *connection_method*
is `SZLLoader.RemoteConnectionMethod.Tunneled` or
`SZLLoader.RemoteConnectionMethod.Direct`, this specifies the
username to use when logging into the server. This will default to
the client host's user name.
authentication_method (`SZLLoader.RemoteAuthenticationMethod`, optional):
The authentication method to use when connecting to the remote
server when *connection_method* is
`SZLLoader.RemoteConnectionMethod.Tunneled` or
`SZLLoader.RemoteConnectionMethod.Direct`. Possible values are
`SZLLoader.RemoteAuthenticationMethod.SSHAgent`,
`SZLLoader.RemoteAuthenticationMethod.SSHPrivateKey` (default)
which uses the file specified by *ssh_private_keyfile* or
`SZLLoader.RemoteAuthenticationMethod.Password` which will prompt
the user for the remote login password in the console.
ssh_private_keyfile (`pathlib.Path` or `str`, optional): When *server* is
specified and *connection_method* is set to
`SZLLoader.RemoteConnectionMethod.Tunneled` or
`SZLLoader.RemoteConnectionMethod.Direct` and when *authentication_method*
is set to `SZLLoader.RemoteAuthenticationMethod.SSHPrivateKey`, this
specifies the full path to the private SSH keyfile. This parameter defaults
to ``~/.ssh/id_rsa`` where ``~`` expands out to the local user's home
directory.
Returns:
`Dataset <tecplot.data.Dataset>`: The `Dataset <tecplot.data.Dataset>` holding
the loaded data.
.. note:: **Absolute and relative paths with PyTecplot**
Relative paths, when used within the PyTecplot API are always from
Python's current working directory which can be obtained by calling
:func:`os.getcwd()`. This is true for batch and `connected
<tecplot.session.connect()>` modes. One exception to this is paths
within a macro command or file which will be relative to the |Tecplot
Engine|'s home directory, which is typically the |Tecplot 360|
installation directory. Finally, when connected to a remote (non-local)
instance of Tecplot 360, only absolute paths are allowed.
Note that backslashes must be escaped which is especially important for
windows paths such as ``"C:\\\\Users"`` or ``"\\\\\\\\server\\\\path"``
which will resolve to ``"C:\\Users"`` and ``"\\\\server\\path"``
respectively. Alternatively, one may use Python's raw strings:
``r"C:\\Users"`` and ``r"\\\\server\\path"``
