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 […]
Problem: Image resolution on the workspace is distorted. This can include transparency to the desktop, a black screen or scrambled images. Solution: Please ensure that you have installed and updated your hardware graphics drivers. This can be done via the terminal or GUI depending on the graphics card you have. Once you have been able to install or update, run Tecplot again and see if this fixes the issue. For […]
Problem: AVI files saved on Mac OS X 10.8.2 do not play in QuickTime. Solution: When saving an AVI file on a Mac the produced file will prove incompatible with QuickTime X. It has been found that QuickTime X does not support many codecs that previous versions used too. Thus the solution is to use another player. AVI files have been found to work properly on Mac OS X 10.6.8. […]
Note: With the release of Tecplot 360 EX for Mac the use of an X server is not needed. Tecplot is now native to the Mac so this is no longer an issue with Tecplot 360 EX. Download the latest release or get a free trial. Problem: When opening Tecplot 360, the initial Tecplot window appears, however, Tecplot appears to “hang/freeze” on a grey screen. Solution: Apple is no longer supporting […]
Problem: Your Tecplot Linux Ubuntu Unity user interface workspace (e.g., Ubuntu version 12.04) may exhibit translucency, that is, all the open application screens remain visible underneath Tecplot. Solution: To disable this translucency you may instruct Linux xlib to manage the colors natively as RGB. Do this by setting the environment variable in a command line, or in any .bashrc or .profile file: export XLIB_SKIP_ARGB_VISUALS=1
Problem: I exported an EPS file from Tecplot 360 and when I viewed that file in Ghostscript, or converted it into PDF and then opened it in Adobe reader, it had mysterious white grid lines in it. How can I make those white lines go away? Solution: The white grid lines are the result of the default display settings in Ghostscript and Adobe. For both applications, changing one display setting will make […]
Question: How does Tecplot calculate cell or face-centered quantities? Answer: Tecplot uses simple arithmetic averaging to calculate cell- (face-) centered quantities. Integrations are done using the trapezoidal method, which is second-order accurate. For each cell, the cell-centered value of the quantity being integrated (integrand) is multiplied by the volume of the cell, and the result is summed over all cells. If the integrand is node-centered, the cell-centered average is calculated […]
Problem: How can I add line breaks into the line legend labels? Solution: If you define the line mapping name as the variable or zone name, add \n to the variable or zone name (defined in Data > Data Set Info) at the desired location of the line break. If you are using a static Map Name defined directly in the Mapping Style dialog, add \\n at the desired location of the line […]
Problem: How can I quickly round data to a specified level of precision in Tecplot 360 or Focus? Solution: The “round” function can be used to round the values of a variable and either store the result in the existing variable or create a new variable. After loading your data, go to Data > Alter > Specify Equations and enter the following equation: {RoundedData} = round({Data}) In this example, a new variable […]
Problem: How can I calculate the velocity magnitude in Tecplot 360 or Focus? Solution: There are two methods, which are described below: General method (works in Tecplot 360 and Focus) In this method, the mathematical definition of vector magnitude is entered and the calculated result is stored in a new variable. After loading your data, do the following: Go to Data > Alter > Specify Equations and enter the following equation: {Velocity Magnitude} […]
