Hi Wolfgang
Using MappingQ(2) solved the problem, thank you!

doesn't know which array it subscripts.

I am working on a combined stokes laplace problem (I also attach the code).
Essentially I am solving stokes in one part of the domain and laplace in
another. To this extend, I want my velocity to be both continuous and and
have continuous first derivatives everywhere in my domain (
