![]() ![]() Let’s say you only want to edit a specific portion of your dataset. To see a full example of the bracket syntax, watch Comparing Grids in Tecplot 360. The result will be applied only to the first zone due to the selection in “Zones to Alter”. This will create a new variable called “delta_Vmag” which takes the difference of the tenth and first zone. If you wanted to compare two zones, find two zones of identical grid structure and enter the following syntax: 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.įor this example, only the second zone will be edited and Vmag will be calculated using only its velocity components. A full list of functions is located in Section 20 – 1.1, “Equation Syntax” in the User’s Manual.įor our velocity magnitude calculation, all three of these equations will achieve the same result. Notably, squared or second power is indicated by a double star. A complete list of variable assignment letter codes is available in Section 20 – 1.1, “Equation Syntax” in the User’s Manual.Ĭommon mathematical functions such as SIN, COS, SQRT, and other common mathematical operands are available in the equation syntax. ![]()
