I load the fluent "*.cas and *.dat" and then play the macro in http://download.tecplot.com/macros/Qcriterion.mcr
But it shows "enter the variable number" What the variable number means? is it the nodes number of my own structure or the range of the x axis or the number of points need to paint. I don't know. So I ask for help.

I believe the macro is looking to confirm (and matchup) the name of the variable of velocity in the x direction (typically labeled U). The macro will also go on to ask for the name of the variable in the y & z direction (typically labeled V & W).

I have another suggestion that I would like you to try. In Tecplot 360’s top menu line click on “Data” the “Data Set Info..”. A table of variables will appear. From that list there will be a number associated to the xvelocity (and y & z velocity), it may be something like “4: xvelocity, 5: yvelocity, 6: zvelocity”. It is this number that the macro may be seeking for the variable number.
So at the macro prompt, enter the variable number that is next to xvelocity variable name. In this example is would be 4 for U.

Qcriteria and Lambda 2 improvements

#9 
Member

Hi All,
We will be making the qcriteria and Lambda 2 available later this year in the main interface of Tecplot 360 EX to improve the ease of use. I would recommend that you join our beta program at the link below to be among the 1st to try the new technology. http://www.tecplot.com/my/beabetatester/ also check the whitepaper on vortex topography here: http://download.tecplot.com/docs/Som..._Revisited.pdf Durrell
