Data comparision using 'if' for tecplot macros
 

Hi,

I've written a macro for comparing my output data to a constant value. My output file is a 3-dimensional block type data. In total there are 120 zones and 19 variables. I want to compare each and every point from all the zones with a constant value. I'm trying to compare the variables value like this :

$!LOOP |var|
----
----
$!LOOP |zone|
----
----
$!IF |V|var|[|zone|](i,j,k)| == 1
$!ALTERDATA
----
----
$!ENDIF
$!ENDLOOP
$!ENDLOOP

var - variable number ;
zone - zone number;
i,j,k - indexes of an arbitrary point;

but it's saying that's not the correct format etc.

Could someone help me with this?

Thanks,
Othniel

In your case I would first apply the operation "Value Blanking"

Hi,

Thanks for the reply. Actually I can understand what you are saying. If we use 'value blanking' we can eliminate data which we don't need, but in this case I want to further modify the data after comparison with the constant value. Like, I want to count the number of data points whose value is equal to 1. I would like to know how to correctly use the IF statement there.

Thanks,

In this case the best way (ImHO) it is use "Integrate" option.
