I use openFoam to run a multiphase case, but the code doesn't put out the data of vortex, how can I draw vortex by paraview?

dear Wais
you can add this code into creatFields and see the vorticity:

volVectorField vorticity
    (
        IOobject
        (
            "vorticity",
            runTime.timeName(),
            mesh,
            IOobject::NO_READ,
            IOobject::AUTO_WRITE
        ),
        curl U
    );

or you can Add "curl(U) leastSquares;" into gradSchemes block (fvSchemes dictionary). After that, you run the utility 'vorticity'

I think the two methods calculate the vorticity, and I want to know how to put out vorticity? Maybe I will add vorticity file to 0 folder?

you must go to the fvSchemes in system folder and add

curl(U) leastSquares;

into gradSchemes block
After Run your case type in terminal:

vorticity > Vortex

know you can see mount of the vorticity in Vortex in your run folder.

Could I draw vortex by lambda 2 method?
