What's New

Tecplot Focus 2020 R2

Release Date: December 9, 2020

  • Ability to split a zone into distinct connected regions – A command has been added to the macro language to create new zones from isolated regions in one or more finite element zones.

Macro: $!ExtractConnectedRegions

  • Reference variables by name – Tecplot Focus can now save variables by name in macros, layouts, and stylesheets and use names when loading data and retaining the existing style. This capability must be turned on in the tecplot.cfg file. See:

$!Compatibility UseNamesForVariableAssignments = YES

Setting this to “YES” will instruct Tecplot Focus to save variable references by name instead of number. Note that if you have duplicate variable names or variable aliases Tecplot Focus will pick the first variable matching that name.

  • Platform support changes
    CentOS 8.0 and macOS Big Sur (macOS 11) have been added as supported platforms.

Operating System Support

Tecplot aims to support desktop operating systems (Windows, MacOS, RedHat, SLED, Ubuntu) that are under standard maintenance by their manufacturers, and are available at the time of the release of a Tecplot product. Tecplot does not guarantee, but may choose to support, platforms which are under an extended support policy, such as Windows “Extended Support” or RedHat’s “Extended Life-cycle Support.” For MacOS, Apple does not have a well documented OS support policy. Tecplot intends to support the current MacOS and two previous MacOS versions.




Create, Alter and Transform Data: Alter data or create new data using mathematical expressions. Store mathematical expressions. Create mirror images of data. Create new data as subset of existing data. Write conditional expressions using the IF() function. Rotate and duplicate data around an axis.

Interpolate Data: Choose from linear, inverse-distance, and kriging interpolation.

Triangulate: Create sets of triangles from data points defined in a 2D plane.

Discrete Fourier Transform (DFT): Transform one- dimensional ordered linear data into the frequency domain for visualization and further analysis.

Multiple Datasets (up to 5 million points): Create and display plots from many different sets of data simultaneously. Use Variable Combining to combine variables with the same meaning but different names.

Multiple Zones and Variables: Include up to 1 million variables per data set, and up to 1 million zones per data point.


Slicing Tool: Interactively slice 3D volume and surface data displaying mesh, contours, and vectors on the slice plane. Set slice orientation by selecting 3 points.

Iso-surface Tool: Change iso-surface values interactively.

Probing Tool: Click on the surface to display interpolated variable values and cell indices. Snap selections to nearest grid point.

Streamtrace Tool: Interactively seed rakes of streamlines, streamrods, and streamribbons in 2D and 3D. Specify lines to terminate streamlines. Display markers along streamlines spaced by vector magnitude. Place streamline rakes. Generate surface streamtraces on a no-slip wall based on shear stress vector field. Auto seed a specified number of streamtraces on a selected surface.

Contour Tool: Interactively add and delete contour lines or levels.

Extraction Tools: Interactively define sets of points or polylines to which 2D and 3D surface data is interpolated and extracted for display as a separate plot.

Curve Fits: Use least squares linear, polynomial, power, and exponential curve-fits. Use least squares curve fit of a linear combination of specified functions.

Data Blanking and Clipping: Set multiple constraints (or masks) to blank the display of data based on local field variables, functions of variables, grid indices, or depth from viewing position. Clip surfaces of 3D volume data to reveal internal variations. Omit zones or peel away surfaces to highlight specific details.

Data Extraction: Extract iso-surfaces, slices, subsets, streamtraces, polylines, the surface 3D volume finite-element data, and point sets from 3D data to new data segments (zones) for further plot customization.


Configuration File and Batch Files: Set new defaults and perform initialization with configuration files and start-up batch files.

Macros: Use macros to perform multiple, repetitive changes.

Layout Files: Return to plots exactly as you created them by saving a layout file recording the frames, plotting attributes, and the data. Apply layout styles to the same data set or different datasets.

Stylesheets: Record all aspects and appearances of a plot frame in a stylesheet without the data. Apply a stylesheet to recreate a previous plot or to apply plot styles to another set of data.


Cross-Platform Capability: Run Tecplot Focus on Windows, Mac OS X, and Linux platforms. Interchange Tecplot Focus macro files, layout files, stylesheets, color map files, and data files between all platforms.

Expanded Data and File Sharing: Loads PLT (*.plt), which is compatible with Tecplot Focus.

Plot Annotation

Mesh layer: Display 1D, 2D, and 3D grids. Color mesh lines by variable, and remove hidden lines.

Contouring: Display contour lines, color flood between contour levels, and color fill cells (or elements). Use multiple contour variables to view and analyze interrelationships among several variables simultaneously.

Vectors: Display 2D and 3D vectors on planes, 3D surfaces, and in volumes. Display 3D vector components tangent to 3D surface. Specify length, color, line type, and head style. Color by variable.

You do not need to uninstall the trial version. The installation of Tecplot software remains the same regardless of the license type.

Q: If I want to install Tecplot Software on a new computer, is a new license key needed?

The answer depends on which type of license you have.

Single-user license

If you have a single-user license, use your Activation Code to run Tecplot software on up to 3 computers. If you are not using an Activation code, you will need a new license key to migrate your Tecplot software to a new computer. You can request a new license key (up to 3) from our customer portal,My Tecplot (link at top of page).

If you do not have a current TecPLUS service, please read our Support Policy.

Network license

If you have a network license, you will not need a new license key. Install your software on the new computer, choose the network install mode, and include your license server name when prompted. Your software should run successfully as long as your license manager is set up correctly.

Q: Can multiple versions of Tecplot software be run on the same computer?

Yes, multiple versions of Tecplot software can run on the same computer. Similarly, Tecplot Focus, Tecplot Focus, Tecplot RS can be run on the same computer.

Q: Can Tecplot Focus, Tecplot Focus, and Tecplot RS be run on the same computer?

Yes, the products can run on the same computer without conflicting with each other.

Q: Can Tecplot softare be run on a virtual machine?

With a network license, Tecplot software can be run on a virtual machine.

A single-user license key does not allow running on a virtual machine. If you need to use Tecplot software on a virtual machine with a single-user license, please email Technical Support to explain your situation.
