![]() Tecplot uses the number of values on the first row to determine how many variables there are. You can change this from within Tecplot once the data is loaded. ![]() Tecplot will assume that the first variable is the X coordinate, the second the Y coordinate, and If your data is a simple plot, then you need only have it in a file with the values seperated by spaces or linebreaks. More information on preplot can be found in section 7.1 of the Tecplot manual. If you are going to be using the same set of data more than once or twice, it is probably best to run preplot so that you can load it more quickly. In Tecplot 360, users may need to create a geometric region to perform operations such as extracting or blanking data. The file type is HDF5 and is loaded similar to the 2D pipe flow data shown previously. The velocity in the x,y, and z-directions are the outputs to be visualized. The following example is for pressure drive flow over a sphere placed at 0.25 H. You can create a binary file from an ASCII file by running the program preplot on your data. One final example of Tecplots post-processing is for 3D computational fluid dynamics (CFD). Tecplot can either read ASCII (text) data files or data files in a Tecplot specific binary format. There, input files are gone over in more detail. If you are going to be loading in more than a few variables, or want to create a complex plot, then you are strongly encouraged to read chapter 6 of the Tecplot manual, available in the Barker Library stacks. However, it needs to have a fairly strictly formatted input file. Tecplot can handle very complex input data. ![]()
