The goal of these Getting Started with Tecplot 360 training sessions is to increase your efficiency when visualizing and analyzing CFD results. Each session uses a different dataset, so they cover slightly different capabilities. But all sessions cover the basics: user interface, loading data, creating slices, iso-surfaces, and streamlines, and exporting images, animations, and videos. If you have a recommendation for an upcoming training session, we would love to hear about it.
No, the georeferenced image was not in the netCDF file. We used the tool QGIS to create that image. If you are not familiar with QGIS, it is a free open source tool. If you need help creating images using that tool, our support staff does have some experience with it. We are not geoscience experts here at Tecplot, but can help with some of these file formats.
Schlieren images are frequently used for a high-speed aircraft. Tecplot 360 cannot create Schlieren, but it can do Shadowgraph. If that is a good alternative for you, here are two video tutorials that may help:
This is not built into the Tecplot 360 directly, but we have written a Python script for this purpose. The Python script requires FVCOM data and the use of the siglev variable. Here is a video tutorial to walk you through Computing a Vertical Transect in Tecplot 360.
The best way to calculate a new distance variable along the X-axis is to use our Python API, PyTecplot. At each point you will be able to get the X and Y values and compute distance using the Pythagorean distance. Our Support Team can certainly help you with the script.
One way to show real-time values in an animation is to create a text box, click to place it, and then use dynamic text. The dynamic text, &(SOLUTIONTIME), refers to solution time. As you step through time, the solution time will update and show the current value on the frame itself.
As you animate, or progress, through time, Tecplot 360 will continue to load data, and so you will see an increase in the amount of RAM used, but never fear! Tecplot 360 has an intelligent strategy for offloading data, which frees up RAM. The oldest data is offloaded first, using a cell-aging algorithm. For batch mode operations or movie file exports you may want to adjust the Load-on-Demand settings to Minimize Memory Use. This can be found on the Misc tab in the Options>Performance dialog.
One more thing to note if you have cell-centered data in your dataset, many Tecplot 360 algorithms require that data be interpolated to the nodes. This is important because nodal values are computed, and then stored in a temporary location. This is done so the nodal values do not have to be recomputed later. We have had a few people run out of disk space because they were doing many computations on large simulations. To prevent running out of disk space, make sure that your temporary directory has plenty of room. Tecplot 360 has options to specify the temporary directory location.
The answer is no, currently not, but we have experimented with a loader to do that. If you need this capability, please contact us at sup...@tecplot.com, and we can work with you to update the loader.
The answer is maybe. Certainly, Tecplot 360 can import any image into the plot. If you have an image, you need an associated world file, in this case a PGW file (a PNG world file) which defines the region of that image. If you do not have a world file, you can import the image and then pan and zoom to get it to line up with your data.
A polyline will not work for this, but there is a way to show the behavior of the variable over time at a specific point. Use the Probe tool to create a time series plot. At the probed area, Tecplot 360 will extract a new region of data at that specific point. This new region can be used to show a line plot of that variable over time. The two plots are automatically linked, so when you step through time, you will see the salinity (if salinity is the variable) behavior at that point. And then you will see the bar indicating the current time step at that point.
2D and 3D plots can be animated through time, but XY line plots do not have the capability. To get around this, you can represent a line plot using the 2D plot type. You will not have the multiple Y axes capability, but you can simulate a line plot using the 2D plot types.
Many FVCOM models have solution times are Number of Days since a specific date and time. Tecplot 360 does not inherently display a date and time. However, you can use a PyTecplot script to add Auxiliary Data to the zones that include the actual time.
An iso-volume is an important concept when you need to quantify the volume occupied by scaler or a set of scalar values. In ocean sciences, an iso-volume can be used to visualize and quantify values, like dissolved oxygen, an indicator of poor water quality. In diesel engines, an iso-volume can be used to identify regions in the cylinder contributing to emissions.
In this case, we want to identify regions where NOx is greater than .005 and temperature is above 2,000 Kelvin. To isolate this region, we will use value blanking to eliminate the regions where NOx and temperature are below our target values. Both NOx and temp are cell-centered variables, so we blank the cells when the primary, or cell-centered value, is blanked.
Now we want to plot the results so we will toggle off Show tabulated results and toggle on Plot results as. Clicking Integrate will plot the results.
The system was modeled in Fortran by Dr. Mark Person, who is my advisor. It is a two-dimensional model capable of simulating groundwater, heat and solute transport, as well as tectonic evolution and petroleum generation. With no surface expression, it is a blind geothermal reservoir, however there is one geothermal well with temperatures of 99 C at 371 m depth and a total dissolved solid of 1900 mg/L.
The second challenge was to image the geothermal upflow zone and determine the salinity and lateral extent of the system. We extracted salinity in Tecplot 360 and then post processed in R to convert from model salinity to formation resistivity. The 2D formation resistivity plots were used to compare to the formation resistivity data we collected with surface electrical surveys (transient electromagnetics). The collected data, which are also 2D plots, were interpolated and contoured in Tecplot 360.
Over the past decade the research group I worked in has been the primary developer of the model CE-QUAL-W2, a 2-dimensional, width-averaged hydrodynamic and water quality model that predicts temperature, flow, water level, dissolved oxygen, pH, algae, and other water quality constituents.
If we need to make many plots, we use the macro abilities of Tecplot 360. We also use macros to post-process model predictions to create static x-y plots. We usually generate WMF images which are then imported into our reports and PowerPoint presentations.
We also use Tecplot 360 for the annual Water Quality Workshop that we teach every June. In the computer lab section of the workshop, we use Tecplot macros to rapidly process the predictions of the model example problems that the participants are working on. This allows participants to learn more quickly about the CE-QUAL-W2 model and learn more about Tecplot 360!
The class is taught to professionals (engineers, managers and scientists) who would like to apply the water quality model CE-QUAL-W2. Over the past decade, Portland State University has been the primary developer of CE-QUAL-W2.
Q: Where do I download the latest software version?
Tecplot 360 can be downloaded through our customer portal, My Tecplot link in the top menu. You will be prompted to log in to access the software downloads. If you do not already have an account, you can request one.
Q: How do I export an image when I have hundreds of zones?
If you have hundreds of zones it can be time consuming to switch to each zone and export an image. Macros can be used here to automatically activate each zone in succession and export an image.
Then edit the macro file using a text editor and encase the export and activate call in a LOOP and ENDLOOP. Check the Scripting Guide in our documentation for additional information about these commands.
Q: Can my older version of Tecplot 360 read .szplt format?
Newer Tecplot 360 versions are backwards compatible with earlier versions of Tecplot 360.
Versions of Tecplot 360 released before 2014 cannot read SZL (.szplt) file format. We recommend updating to the newest version.
Q: How do I set-up transient (time-varying) animation in Tecplot 360?
The Edit Time Strand tool can be used to set-up your data to be recognized as Transient. A Strand and SolutionTime will need to be assigned for each zone. Zones that are active at the same time step need to share SolutionTime, but have different Strand IDs.
Q: What platforms does the latest version of Tecplot 360 support?
Platforms supported by the latest version of Tecplot 360 are listed in Documentation & Platform Requirements. You can also find requirements in the Installation Guide or linked from the Tecplot 360 Welcome Screen.
SZL stands for subzone load-on-demand. It is our proprietary technology that increases memory efficiency by combining data management algorithms, advanced data requirement predictors, parallelization and additional code optimizations.
Q: I installed the trial version, do I need to uninstall it before installing my purchased version?
You do not need to uninstall the trial version. The installation of Tecplot software remains the same regardless of the license type.
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 360, Tecplot Focus, Tecplot RS can be run on the same computer.
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 discuss your situation.
