Hi, I can calculate vorticity during running time by adding functionObject "vorticity" in the controlDict, so the vorticity file is created for each time directory. But I cannot generate too much time directories due to the memory limit.
Is there any way to generate a series of, like vtk files of vorticity in the post-processing folder, similar to the cuttingPlan of U and p?

Thanks!
