Value at boundary in one physics used in PDE of another physics under same component model

Dear All,

I have a 1-D model that contains two Coefficient form PDE physics.

I want to take the value of the dependent variable of physics 1, evaluated at the boundary of my 1-D geometry and use this value in the Coefficient form PDE of physics 2.

I tried using the extrusion operator (linear and general) at the boundary to get the value of my dependent variable in physics 1 and use that in the PDE of my 2nd physics but was not successful. I get an error that states variable (that is extruded and used in the physics 2) is not defined.

Any help or pointers is much appreciated.

Thanks
Vishnu
