Internal boundaries in fortran interface

[konstpas]

Hello,

I'm using the AMReX fortran interface to solve the heat equation in my code. I recently came upon the need to model cases where cells that are adjacent to each other have zero conductivity on their interface. I'm worried that calls to amrex_fillcoarsepatch and amrex_average_down will smear out temperatures between cells that have zero thermal conductivity in their interface. Is there a way to avoid that that in the fortran interface? Am I correct in understanding that embedded boundary conditions are not supported in the fortran interface?

Thanks,
Konstantinos
