Errors with three subdomains mesh with interface transfer

[salaudeen-ya]

Hi all,

I am trying to have three subdomains for a simple BVP. My two-domain works just fine, but I have errors with three subdomains.

My input file and error message are attached.
Thanks

Kindly help.

Hello

You made a tree of mesh generators that has multiple outputs.
Try chaining all the mesh generators, making each MG the input = of the one below it
