## Weighted versus Arithmetic Averages and Tecplot

Question: Why is there a difference in Tecplot’s integration average results and the average, or mean, I am calculating over all the data values? Example: I have nodal data and I want to calculate average U velocity on the following domain (see Figure 1). When I use the integration average feature (Analyze>Perform Integration…>Average>U), I calculate 38.90 m/s. But when I calculate the average over all the nodal U values in […]
