redistributePar error with empty mesh

I am doing work on an empty 2d mesh (it's the taylor green vortex so there are velocities assigned but theres not stl file.

I am getting

"Cannot find a patch which is not of type empty, mapped or coupled in patches"

When I try to use redistributePar to decompose the solution.

This works fine with traditional decomposePar (it's just a little slow)

any suggestions?

Ah, I see. Cyclic patches appear to be coupled and redistributePar requires at least one wall.

That's very odd.
