Problem: I want to display the solution time on my plot. Solution: Use dynamic text to refer to Tecplot’s SOLUTIONTIME variable. Navigate to the Insert>Text menu and click on the plot to open the Text Details dialog. Refer to the SOLUTIONTIME variable using the following syntax: &(SOLUTIONTIME) Please see the User’s Manual for a list of available options regarding dynamic text formatting. For example, to format the solution time […]
Problem: I want to perform a clip plane. Solution: Use a set of macro commands to clip above/below the defined slice. The macro command related to the clipping of planes is: $!SliceAttributes 1 ClipPlane. It can take the following arguments: AbovePrimarySlice, BelowPrimarySlice, and None. Consider adding these macros to your Quick Macro Panel for faster access: $!MacroFunction NAME = “Clip above primary slice” ShowInMacroPanel = TRUE $!SliceAttributes 1 ClipPlane […]
Problem: My solution time is in seconds (ssss.ss), and I want to display it as hours:minutes:seconds (hh:mm:ss.ss). Solution: Use a Tecplot macro to loop over time and retrieve the solution time. Assign the hours, minutes, and seconds to new variables and refer to their max values using dynamic text. Macro Procedure (see link to the GitHub script below): Retrieve the number of time steps: $!EXTENDEDCOMMAND COMMANDPROCESSORID=’extend time mcr’ COMMAND=’QUERY.NUMTIMESTEPS […]
This article describes both a macro and a PyTecplot script that extracts a field variable along a line normal to a surface. We recommend using PyTecplot insofar as possible. Example: Load the M6-Wing example file, which can be found in your Tecplot Installation Directory: …/Tecplot/Tecplot 360 EX 20xx R1/examples/OneraM6wing/OneraM6_SU2_RANS.plt. To better visualize the node at which we’ll probe, let’s turn on the mesh for the second zone. Zoom somewhere on […]
Problem: I am displaying one axis in my 3D plot, but my data interferes with it (see Figure 1). How do I offset my axis away from my plot? Solution: Change the minimum value of the vertical axis range in that view. In the case of Figure 1, the Z axis range minimum needs to be decreased. For this example, 1) Go to Plot>Axis… and select the Z axis and […]
Question: At high magnification, my cell and point labels become grainy and look terrible. How can I display these labels correctly? Solution: Use software rather than hardware rendering to display these node labels on a highly zoomed plot. See Figure 2. 1) Download software_hardware_rendering_qmp.mcr from our GitHub or create a macro with this code: #!MC 1200 $!MacroFunction Name = “SwitchToSoftwareRendering” SHOWINMACROPANEL = true $!Page UseSoftwareRendering = true $!EndMacroFunction $!MacroFunction Name […]
In the release of PyTecplot 1.0, Frame Linking has been implemented in the API. Frame Linking allows users to quickly link attributes of frames together like position, 3D view, and solution time. To link the view simply implement the following commands on both frames: for frame in tp.frames(): plot = frame.plot(PlotType.Cartesian3D) plot.activate() frame_linking = plot.linking_between_frames frame_linking.group = 1 frame_linking.link_view = True frame_linking.link_solution_time = True This allows all of the frames […]
Question: I am running out of memory rendering my fine-mesh data. How do I read-in a smaller, decimated version of my ordered dataset into my layout? More details: If you are working on a computer with limited resources, some processes can surpass the available computer memory. If you are unable to add more RAM, this can cause Tecplot to slow or, at worst, crash. Try this solution if some actions […]
Question: How do I change the name of a variable in the contour legend box? See Figure 1. Solution: Renaming a contour variable requires altering the variable name in the Data Set Information dialog box: 1) In Tecplot 360, go to Data>Data Set Info… (see Figure 2). 2) Double-click the name of the variable displayed in the contour legend and replace it with the desired name. Voilà, the contour legend […]
Problem: I receive the following error when running Tecplot on Linux platforms: /tec360-bin: symbol lookup error: /lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var Solution: This issue typically happens on newer versions of Linux. To fix this, delete libfreetype.so.6 from the Tecplot ../bin directory.
