v10 had a statistics addon that could be activated from the tecplot.add file. Simply uncomment the \$!LoadAddon and the statistics addon will run, and you can compute a mean value. Conversely, if you want to compute a mean over the entire data set for each point, you can try the following:

#!MC 1000

\$!PromptForTextString |ZonesPerSoln|

Instructions = “Enter the number of zones per solution:”

\$!VarSet |NumSets| = (|NumZones|/|ZonesPerSoln|)

\$!Loop |NumSets|

\$!VarSet |EndZone| = ((|loop|-1)*|ZonesPerSoln|)

\$!VarSet |BeginZone| = (|EndZone|+1)

\$!Loop |ZonesPerSoln|

\$!If |BeginZone| == 1

\$!DuplicateZone

SourceZone = |loop|

\$!EndIf

\$!If |BeginZone| > 1

\$!VarSet |NextZone| = (|BeginZone|+|loop|-1)

\$!VarSet |LastZone| = (|ZonesPerSoln|*|NumSets|+|loop|)

\$!ActiveFieldZone = [|NumZones|]

\$!Loop |NumVars|

\$!AlterData [|LastZone|]

Equation = “v|loop| = v|loop|[|NextZone|]+v|loop|[|LastZone|]”

\$!EndLoop

\$!EndIf

\$!EndLoop

\$!EndLoop

\$!Loop |ZonesPerSoln|

\$!VarSet |LastZone| = (|ZonesPerSoln|*|NumSets|+|loop|)

\$!Loop |NumVars|

\$!AlterData [|LastZone|]

Equation = “v|loop|=v|loop|/|NumSets|

\$!EndLoop

\$!EndLoop

This should provide you a simple macro that will enable you to average all the data across multiple solutions assuming each solution has the same number of zones, and that each zone in that set corresponds to an identical zone in another set in computational coordinate limits.

Good Luck.

Subject: [Tecplot_Talk] Averaging of LES data set.

To Tecplot users:

I have data set computed from LES which can be loaded into the Techplot (I have techplot 10.0 version).
Now I want to calculate mean of all these data set. Structure of each set is as follows:

Data set-1, contains information of X, Y, Z, U, V, W, Temperature for three planes. (plane a1, a2, a3).
like wise I have several data sets and I want to get average of the velocity and temperature variables.

Is there any feature in  Tecplot 10.0 that does this job directly? I will appreciate if anyone can provide
a workable macro for this purpose.
