Tecplot 360 is a powerful visualization tool with the capability of line plotting, 2D and 3D surface plots, and 3D volumetric visualization. The data loader for Tecplot can read a variety of different files such as, HDF, HDF5, Excel, FEA files, and a general text loader. This tutorial will go through the process of generating plots using some of the previously mentioned file types and plot types.
For a Windows machine, Tecplot is started my simply running the executable. For a Linux machine, such as the ones at CAVS, Tecplot can be executed with the following commands:
> swsetup tecplot > tec360
Loading a text (.txt) file
For a general text file, the visualization is pretty straight forward. In this example, stress-strain data of a tensile simulation was output to a text file (stress-strain.txt). After starting Tec360, the welcome screen shown below appears shown in Figure 1,
To open the text file, go to --> File --> Load Data File, and the data file loader box appears. Next, navigate to the directory of the file, (i.e. /scratch/dhj21/tec360), select *.txt as the files of type, and be sure to check the advanced option. The advanced option allows the type of spacing for the text file. For this text file, tab spacing was used. This is shown by Figures 2 and 3.
Tec360 automatically plots the first column versus the second column for this case and reads the first two cells as the x-axis and y-axis respectively. This is shown in Figure 4.
