Nonetheless, these formats may use some lower level library such as HDF5, or they may use raw ASCII. That is, the code that writes these files is typically part of the application itself and is not a stand-alone product of its own. These are formats that were originally designed primarily for and are part of some specific application code.

This updated blog tutorial shows you how to create a new variable which is based on a numeric relationship of existing variables already loaded into Tecplot, see Calculating a New Variable. Read more about this topic in the Tecplot 360 User’s Manual, Section 20 – 1 Data Alteration through Equations. Most notably a double star (**) indicates squared or second power.Īll three of these equations will achieve the same result for our velocity magnitude calculation: In the second case Tecplot’s assigned variables axis or velocity components must be defined.Ĭommon mathematical functions such as SIN, COS, SQRT are included in Tecplot equation syntax, in addition to other common mathematical operands. The second method is referencing the variable assigned to the u and v vector component variables.

The first method is referencing the variable by the variable index. Variables on the right side of equations may be referenced by two other methods:

In Tecplot equation syntax, creating a new variable or referencing a variable by name requires surrounding it in curly braces. Use Data>Alter>Specify Equations (or click the toolbar button) to alter data in existing zones. We will be calculating a commonly desired variable which is often not included in exported data sets: velocity magnitude. The video covers the Specify Equations Syntax in Tecplot 360. This quick tutorial about Data Alter shows you how to do it. « Back to Video Tutorials Tecplot 360 Basics: Data Alter Duration 1:49Ĭhange the values of entire variables or specific data points, or create new variables in Tecplot 360.
