In another version I am trying, I have combined all the pipes into 1 body 1 part
So I sacrifice the structured mesh, in order to remove the complexity of the interfaces later in the setup.

The case runs fine on my PC
But once again, when I try to upload to HPC, I get the two persistent errors
The first error I don't understand at all!
The second is also a mystery since my script looks fine for the dual-time-iterate command!
