Hi,
there is an example in the old wiki showing how to implement a face conductivity,
so that there is a voltage jump across the face. Have a look here:

This example in the new wiki could also be interesting for you:
https://gitlab.onelab.info/doc/tutorials/wikis/Thermics
It is a thermal example with a contact resistance.
I hope this is of some help.
Best regards,
Michael

Betreff: [Getdp] How to define a discontinuous interface condition
Hello Everyone,
I have problem to define a Discontinuous Interface Condition. The basic structure is that there are two 3D cube 1 and 2 sharing a common interface and the 2D side view is like this:
-------------------------------
| | |
| 1 | 2 |
| | |
| | |
-------------------------------
For a static electric problem(laplace equation), given some boundary condition, and a interface resistance--which means that the potential does not continuous in the interface, I want to solve the potential phi.
The phsics at the interface should be \Delta phi \cdot \hat{n} = phi_1-phi_2, where \hat{n} is the normal vector of the interface and phi_1 and phi_2 are the value of potential phi at the interface(actually extremely closing to the interface) from cube 1 and cube 2, respectively.
The problem is that I donot know how to the describe this boundary as a formulation, and I have searched the archive of this mail-list but didnot get good information.
Can you give some suggestion on this kind of interface boundary condition?
Massive thanks in advance!!
Yuanzhi Zhu.
