When working with transient datasets, Tecplot implements “Time Strands”. Time Strands are assigned to a group of zones which represent the same object. For simple transient datasets, sometimes only one Time Strand is used. Whereas more complex datasets will implement multiple Time Strands. For example, if you are plotting a jet, typically there will be one Time Strand per wing, one for the fuselage, and one for the tail. Time […]

Calculating Average Normal Velocity to Iso-Surface
Problem: How do I calculate the average normal fluid velocity (or any vector variable) going through an iso-surface? Details: Or stated another way, “I am trying to use a vector dot product with unit normal integration to get the average normal velocity through an extracted iso-surface.” This question originally relates to this scenario, but it can be used for calculating the average flux though a surface for various cases. Solution: […]
Precise Probe to Create Time Series Plot
Problem: How do I Probe to Create Time Series Plot at a given set of coordinates? Solution: Use Tecplot’s macro language to precisely define the point to probe. The commands are as follow: Prompt for the (X, Y, Z) coordinates of the point to probe: $!PROMPTFORTEXTSTRING |xPosition| INSTRUCTIONS = “Enter X position of the probe.” Or define them directly in the macro: $!VARSET |xPosition|= 0.1 Pass these coordinates to the […]
