Curl of the Velocity field
 
Hi All,

Does any one know how to calculate the curl of the computed velocity field in STAR-CD, (I mean all three components of the vorticity vector i.e. i,j,k).

Thanks

To get the curl you need this command: "operate, gradient, n, 1". But first you need to have vertex data loaded in post register #4.

Enter "help operate" to see the details.

Sorry, I was thinking vorticity. My previous post is incorrect.

The command you want is "operate, curl". Again see the help for the details.

Thanks for the reply Pauli.
