the stationary form of the Coefficient PDE form is

I interpret this equation as

I think in the case where u is a scalar function this is correct. But when for exampleis a vectorlike function I cannot match the dimensions.

For example assume we have

Then

buthas in the COMSOL interfaceentries. How do I match this such that in the end I get a two component vector again?
