Watch our Updated Webinar! You want to learn the basics of post processing with Tecplot 360 in the shortest amo.
Tecplot 360 can read in data produc ed in many different formats using the data loaders provided with the product. This manual describes a complementary approach: writing your data in the Tecplot 360 data format so it can be read natively, providing the best experience for Tecplot 360 users.This Data Format Guide includes the following topics. In this Tecplot support video, we will discuss Tecplot 360's Time Animation feature, which allows you to create animations that display time-dependent struct.

Creating a new variable or referencing a variable by name requires surrounding it in curly braces.
Variables on the right side of equations may be referenced by two other methods: First, by the variable index. Second is to use variable assignment letter codes. In this example, we’re using ‘u’ and ‘v’ which represent the variables assigned to the U and V vector components in Plot -> Vector -> Variables dialog. A complete list of variable assignment letter codes is available in Section 20 – 1.1, “Equation Syntax” in the User’s Manual.
Common mathematical functions such as SIN, COS, SQRT, and other common mathematical operands are available in the equation syntax. Notably, squared or second power is indicated by a double star. A full list of functions is located in Section 20 – 1.1, “Equation Syntax” in the User’s Manual.
For our velocity magnitude calculation, all three of these equations will achieve the same result.
Editing Specific Zones
If you only want to edit or create a variable for one zone, select the zone you wish to use in the “Zones to Alter” field.
For this example, only the second zone will be edited and Vmag will be calculated using only its velocity components.
If you wanted to compare two zones, find two zones of identical grid structure and enter the following syntax:
This will create a new variable called “delta_Vmag” which takes the difference of the tenth and first zone. The result will be applied only to the first zone due to the selection in “Zones to Alter”.
To see a full example of the bracket syntax, watch “Comparing Grids in Tecplot 360”.
Using IF statements
Tecplot Focus Tutorial
Let’s say you only want to edit a specific portion of your dataset. You can specify these conditions with an IF statement. Let’s take the Vmag variable we have already created and make it 0 outside of a specific region:
Tecplot Tutorial
This equation reiterates our Vmag calculation and then adds our IF statement. This IF condition makes all of the Vmag values outside our bounding box, equal to zero. Our bounding box chosen in this situation is X from -5 to 5, and Y from -5 to 5.
