Updates & Features

  • TecIO: If you choose to use Boost 1.75.0 or greater, you will need C++14. You can use Boost 1.69.0, in which case, you do not need C++14.

  • List of data loaders in the File > Load Data dialog have been alphabetized to make loader selection easier. Tecplot file format loaders remain listed at the top.

  • Updated the Probe Dialog to allow adjusting the numeric precision. The eliding (the ‘…​’ in the right-hand image) was also updated to be in the center. These two changes make it much easier to recognize the order of magnitude of the probed values.

probe 18 precision

Bug Fixes

  • Fixed crash with surface streamtraces placed on no-slip wall zones.

  • Fixed crash when changing solution time while a LineMap is selected and there are 2D or 3D Frames with linked solution time.

  • Eliminated a benign command line warning: "libpng warning: iCCP: known incorrect sRGB profile", which was displayed on Linux operating systems.

  • Windows Installer now installs additional dependencies which prevented some Tecplot add-ons from loading.

  • Implemented TecUtilDialogLaunch(Dialog_ZoneMapStyle) to allow the Zone Style dialog to be launched programmatically from Tecplot add-ons.

  • Fixed crash with $!CreateFEBoundary macro command with small (~ < 2500 cells) surface zones.

Usage Data Collection

To help us better understand how our customers use our products and improve them further, Tecplot Focus includes an analytics feature that reports user activity over the Internet using the Google Analytics™ platform. This feature tells us which dialogs you use and which controls you manipulate in them. However, to protect your privacy and trade secrets, we do not see names associated with your data (such as variable, zone, or file names) or the actual values of fields in dialogs, nor do we receive any information about you or your organization’s identity.

If you do not wish to participate in this program, turn off "Collect Anonymous Usage Data" in the Help menu.

We receive basic information about your operating system, product version, and license at each launch of Tecplot Focus, even if you have opted out of the usage data program. This information is not tied to any usage data collected.

No usage data of any kind is collected if you do not have access to the Internet or if the Google Analytics service is blocked by a firewall.

Crash Reporting

Please help us make Tecplot Focus better by sending a crash report to us in the event that the application terminates unexpectedly.

On Windows, Tecplot Focus creates a crash dump file. You will receive a message indicating that a crash dump file has been created. Click Yes in this dialog to open the folder where the file is created. You can then e-mail the most recent .dmp file in this folder, along with a description of what you were trying to do, to support@tecplot.com.

On other platforms, no crash dump file is created. However, we urge you to send us a report anyway with as much detail as you can remember.

If you have a moment and a desire to be extra helpful, please re-open Tecplot Focus and choose Enable Diagnostic Logging in the Help menu. Then redo the steps you took to cause the crash. Tecplot Focus will record your actions as a macro file. If you are able to reproduce the crash, send the resulting .mcr file to us (along with the .dmp file if you use Windows). On non-Windows platforms, you can find the .mcr file in /usr/tmp/tecplot_$USER/tpa_diagnostics.

Crash dumps and diagnostic macros are stored in a temporary folder and will be eventually be deleted by the system. There is no need to delete them manually.

Graphics Drivers

For best results, please make sure that you are using the latest graphics drivers compatible with your hardware and operating system. These can be obtained from your graphics adapter vendor’s Web site. Old versions may have issues with Tecplot Focus, especially with larger data sets.

Platform-Specific Notes

This section details potential issues specific to your operating system.

Windows

Your account must have administrator rights on your computer to install Tecplot Focus, or else right-click the installer and choose "Run as Administrator."

Linux

Temporary Directory

Tecplot Focus relies on being able to create temporary files in the system temporary directory. On Linux, this directory is typically /usr/tmp or /var/tmp. If your user account does not have permission to write into the system temporary directory, you can use a different directory either by setting the TMPDIR environment variable in your profile or by setting the TEMPFILEPATH in the tecplot.cfg file.

Menu Shortcuts

Menu shortcut keys may not work if the Num Lock is on. You may set the Num Lock to turn off automatically at boot in your computer’s BIOS.

SELinux

SELinux (provided with some Linux distributions) adds an extra layer of security. If you see this error message:

//lib/libtec.so: cannot restore segment prot after reloc: Permission
Denied

Enter these two commands, replacing /path/to/tecplot/lib with the actual path of your installed Tecplot Focus lib directory (your account needs sudo permission):

sudo chcon -v -R -u system_u -r object_r -t lib_t /path/to/tecplot/lib/
sudo chcon -t texrel_shlib_t /path/to/tecplot/lib/

You can then run Tecplot Focus without disabling SELinux.

Mac

Keyboard Shortcuts

Previous versions of Tecplot Focus used the Control key for most keyboard shortcuts, rather than the Mac standard Command key. Tecplot Focus EX changes these shortcuts to use the Command key under Mac. Similarly, when rotating a 3D plot, you now hold down the Command key while dragging with the right mouse button.

Note that the Alt key may be called Option on some Mac keyboards.

Right Mouse Button

If your Mac’s mouse has only a single button, hold the Control key while clicking to access right-click functionality.

Middle Mouse Button

There is no functionality in Tecplot Focus that requires a middle mouse button; however, it does provide some shortcuts. Users of single-button mice cannot emulate the middle button, but users of mice with two buttons can hold down Control while right-clicking if their mouse does not support a true middle-button click.

Enjoy Tecplot Focus 2024 R1 and master the view.
