Making threshold for variables in makro

Hi, I want to make a cut off for some data in tecplot. In macros I can call this data by {O} when e.g. using the alterdata command. I want to set {O} to zero when it is below a given threeshold, say 0.05. I have tried $!IF {O}<0.05 {O}=0 $!ENDIF but the first line is not accepted. Thus, my problem a...

Re: Contours on contours

Ok, to make this robust I should look at sign change of v on the curve u=0. This requires knowledge of how the points in u=0 are connected e.g. I should get the connectivity matrix. Is this accessible?

Re: Contours on contours

Hey again and thanks for the fast and long response. My overall goal is to identify points in a 2d flow with u=0 and v=0 for many datasets. I have done this 'manually' by plotting the contours u=0 and v=0 and then zooming in where the curves intersect. I would like to automate this. So another appro...

Re: Contours on contours

Hey Chris, Thanks for the quick response. In Data Set Information then Zone/Var Info there is no I,J,K information. For the original data set it says Zone Type : FE -Quad Pts : 359,601 Elem : 358,400 My original data set is made of only square elements. For the zone extracted from the contour u=0 it...

Contours on contours

Hi guys, I want to find stationary points of a 2d flow. I am trying to do this by making a contour with u=0 and then create a new zone from this. Then, I will make a contour on this zone with v=0 and these points are then the stationary points. The problem is that for the first zone created I cannot...
