Dear getfem experts,

I would like to solve a (relatively simple) problem with jump conditions on an surface S.

More precisely, if O denotes the domain, the variational form is the following :
\int_O \sigma \grad u \grad v dx + \int_S \alpha [u][v] ds = <source terms>
where [u] is the jump of u over S.

Is there some elegant solution to implement this?
If I have to use the level set strategy (NB: the surface is static and I can easily include it in the mesh), how can I translate the \int_S \alpha [u][v] ds integration?

I will be glad to supply you further details.
Thank you in advance for your answer,
Best regards,
Ronan Perrussel
