31 - 3.6   Extract Over Time

The Extract Over Time add-on, which loads automatically with Tecplot 360 EX, extracts iso-surfaces, streamtraces, and points from polyline geometries in transient data. The resulting zones are assembled into a new strand with proper solution times set for each zone.

note00523.pngTo save a layout file, you must also save a data file when using this add-on.

To unload this add-on, add a "#" symbol in front of the following line in your Tecplot.add File.

$!LoadAddOn "tecutiltools_extractovertime"

To use this add-on, go to Data>Extract and select one of the following menu options.

• Extract Slices Over Time - This option has moved to the Extract Slices dialog. See Section 14 - 2 “Extracting Slices to Zones”. The macro, below, can still be used.

• Extract Polyline Over Time - Extracts a polyline geometry to a zone for each solution time. It allows you to define the number of points along the polyline to extract. It has the following requirements:

• The frame must be in 2D or 3D.

• Only a single polyline can be selected.

• The data must be transient.

• The polyline must be positioned over an existing zone.

• Extract Iso-Surfaces Over Time - Extracts an iso-surface to a zone for each solution time. It has the following requirements:

• The frame must be in 3D.

• The frame must contain one or more iso-surfaces.

• The data must be transient.

• Extract Streamtraces Over Time - Extracts a set of streamtraces to a zone for each solution time. It has the following requirements:

• The frame must be in 2D or 3D.

• The frame contains one or more streamtraces

• The data must be transient.

After extracting, the new strand is available and may be animated or saved to a file.

Macro Processing

The Extract Over Time add-on can be invoked from the macro language by using the following commands:

Slices

$!EXTENDEDCOMMAND COMMANDPROCESSORID='Extract Over Time'

COMMAND='ExtractSliceOverTime'

 

Note: Prefer using the $!EXTRACTSLICES macro command instead. See the Scripting Guide for more details on this command.

Iso-Surfaces

$!EXTENDEDCOMMAND COMMANDPROCESSORID='Extract Over Time' COMMAND='ExtractIsoSurfaceOverTime'

Streamtraces

$!EXTENDEDCOMMAND COMMANDPROCESSORID='Extract Over Time' COMMAND='ExtractStreamOverTime'

Geometries 

$!EXTENDEDCOMMAND COMMANDPROCESSORID='Extract Over Time' COMMAND='ExtractGeomOverTime'

Optionally, you may specify the number of points to extract by using the following format:

$!EXTENDEDCOMMAND COMMANDPROCESSORID='Extract Over Time' COMMAND='ExtractGeomOverTime:nnn'

Where nnn >= 2. If this condition is not met when the macro is played back, the action will silently fail and your macro will continue processing.
