Splitting a volume zone?

I am working on post processing a simulation with two domains - an outer stationary domain and a cylindrical rotating domain within. When they're input to Tecplot, the rotating domain requires an axial rotation to get it to the correct position. This works fine for the surface zones as they are either within the rotating domain or not, but I only have one volume zone (Step XXXX Incr 0) that contains both domains. So, when I create an isosurface, the volume of the rotating domain is not axially rotated to where it should be.
I've tried altering the X, Y coordinates using the following equations (ex. for radius 0.009 and theta 3.7309 rad): {X} = IF((X ** 2 + Y ** 2) ** (1/2) <= 0.009, X * COS(3.7309) + Y * SIN(3.7309), X) {Y} = IF((X ** 2 + Y ** 2) ** (1/2) <= 0.009, -X * SIN(3.7309) + Y * COS(3.7309), Y) It seems to be modifying the correct data points (nothing outside of the radius desired is being changed), but it's not rotating correctly. Is there a way I can create a volume zone that only contains the cylindrical rotating domain or split the current volume zone into two parts so I can apply an axial rotation just to the rotating part? If so, can it be done now or do I need to set something up before the simulation? |

Hi Nick,
It sounds like what you need is a feature called "extract blanked zone" which is currently available as as addon if you contact support@tecplot.com and tell them which version you are using. It will be available to everyone in tecplot 360's next release in early 2020. -Devon Tecplot Product Manager |
