Default Vorticity with pimpleDyMFoam

I am trying to get the vorticity using 'postProcess -func vorticity' on a case in pimpleDyMFoam, but I get the following warning message:

Time = 0.2
--> FOAM Warning :

From function bool Foam::dictionary::add(Foam::entry*, bool)

in file db/dictionary/dictionary.C at line 807

Reading "" from line 13 to line 19

attempt to add entry functions which already exists in dictionary ""

Reading fields:

volVectorFields: U

Executing functionObjects

functionObjects::vorticity vorticity writing field: vorticity

When opening paraFoam this vorticity it is clearly not correct.

Using the 'Calculate derivatives - vorticity' under filters gives me the correct results.

1. Is there a way to use the 'postProcess -func vorticity' with a pimpleDyMFoam solver?

2. Is it possible to export the data from 'Calculate derivatives - vorticity' in a text file, like u and p?

All tips and help are appreciated

I am bothered with a very similar trouble, but for forces.

I executed 'pimpleDyMFoam -postProcess -func forces', but only one line was written to .dat file.
