Hi guys,

I have a .DAT file of v-x and v-y which imported to Tecplot looks like this

As you can see the image doesn't capture the full vortex.

Is it still possible to calculate the circulation.

Actually I just want to get the vortex strength near x=0.

How can I just define a closed loop near x=0 and calculate the circulation.

Will this be physically wrong to calculate the circulation near x=0 only.

Sorry a bit noob here, hence doubts.

Thanks a lot in advance.

I am using Tecplot 360 2014.
