If I replaced "cyclic" with "symmetryPlane", then I could run paraFoam even though I still got a series of warnings. I looked into the mesh, and found something strange (see the attachment). I have no idea what might cause this problem.

I got it. After reviewing the previous posts, I wondered if I should number the blocks in the same order. So I did it, and it worked. There was no more strange mesh even though there were some more warning messages.
