\f[
-\lambda\triangle T = \Phi+\lambda_{sf}(T_f-T)
\f]
where
- \f$T\f$ the main unknown is the solid temperature field
- \f$\lambda\f$ is the solid thermal conductivity possibly set by the user (default value is 1)
- \f$\lambda_{sf}\f$ is the fluid-solid heat transfer coefficient set by the user (default value is 0)
- \f$\Phi\f$ is the heat source term set by the user (default value is zero)
- \f$T_f\f$ is the fluid temperature field set by the user

* The class \ref StationaryDiffusionEquation implements a scalar stationary diffusion equation for the temperature in a solid.
