applying sqrt() operation to a DistributedCellField object

[ZiwenH]

By far there are already implementations of gradient, DIV and many other differential operators, as well as +, -, *, / operations. Is it possible to apply sqrt() to a DistributedCellField object?

[JordiManyer]

Just use composition, like in Gridap. I.e

sqrt∘cf

where ∘ is \circ.
