I would like to have FieldView default to my current working directory when browsing for Data Input files, restarts, etc., but the last used directory seems to be the default. Can this be changed? Some users prefer the current working directory to be the default, so we have made this possible by allowing you to set the environment variable FV_OLD_BROWSER_BEHAVIOR=1.
How can I read Tecplot format data into FV? Binary Tecplot format files are among the data types which can be read using the GENERIC Unstructured..& Data Input option. If you have ASCII format Tecplot files, you can use Tecplot’s Preplot converter to make a binary file.
NOTE: This Knowledge Base article only applies to Tecplot 360 2025 R1 and previous. Starting with Tecplot 360 2025 R2, the graphics engine was changed from OpenGL to Vulkan. Problem: On some systems, you may see a partial (right side and bottom) black border around an image exported from Tecplot 360, even when borders are turned off for the frame. This is caused by an off-by-one issue with some combinations […]
Problem: Tecplot 360 EX pull-down menu becomes unresponsive after minimizing on Ubuntu systems. Solution: This can happen because of Ubuntu’s new Unity UI. You may be able to solve this issue by reverting to an older UI. You can do this by using one of the methods below: For Ubuntu 17+ the workaround is to remove libstdc++.so.6 and libgcc_s.so.1 from the bin/sys directory. For earlier versions of Ubuntu: On the login screen, […]
How can I visualize turbulence and flow features using surfaces? The Q criterion, introduced by Hunt et al. in 1988, is commonly used to identify regions of recirculation in flow fields. As of FieldView version 17, Q-criterion is a built-in function available on the Function Calculator, increasing peformance as compared to using this function via feature_detection_formulas.frm available with previous versions of FieldView.
Note: Tecplot 360 EX is native to the Mac and doesn’t rely on an X Windows System. Download the latest release or get a free trial. Problem: Unable to run Tecplot after upgrading to XQuartz 2.7.5 on Mavericks OS X 10.9. Solution: If you are running Mavericks OS X 10.9 (and in some cases 10.8) you may have noticed XQuartz has pushed out a new release of XQuartz 2.7.5. After you have […]
I’ve used the PLOT3D reader in a FieldView version prior to 12.3 to read my overflow-2 data. Are restarts created in that version compatible with version 12.3? Yes, but don’t try editing FVX scripts (.fvx) or data restarts (.dat) to change the data reader name from plot3d to overflow-2 and expect it to work properly, since some derived function names have been changed, (eg. ‘Pressure [PLOT3D]’ vs. ‘Pressure [OVERFLOW]’). Constants […]
Problem: Unable to complete the install of your Tecplot product due to a “Permissions denied” error. Solution: Upon installing Tecplot, if your installation quits before completion with the error message “Permission denied.” This could be due to permission restrictions set by your computer. This has been found to be true for SE Linux but could be true for any secure platform. Another cause for permission issues may be caused by […]
Problem: I get error messages when I try to compile Fortran source code using gfortran on Linux, even though I installed all the necessary “build-essential” gfortran libraries. Unable to compile Fortran source code using gfortran on Linux. Solution: If you are getting error messages when compiling the Fortran source code consider the following. First, the order of calls in the command line is important. Using Tecplot’s simtest.f90 Fortran source code […]
Note: This software version is no longer supported. Download the latest release or get a free trial. Problem: Unable to load PLOT3D data with layout file created from Tecplot 360 2011R2 and before with Tecplot 2012 and later. Solution: From Tecplot 360 2011R2 on the format for loading PLOT3D data has changed. Currently we no longer load solution and function files as one but instead as separate files. In order to load […]
