Hi,

First thanks for your help and sorry for the time of response,

My problem is the following :

I have a turbine blade in a steady flow, the heat flux and the temperature at the interface are given by a CFD solver called SU2. So now i need to implement the robin boundary condition. In my case the expression is the following :

<https://lh3.googleusercontent.com/-Zo6LzlAt6nA/V2FDcv7cheI/AAAAAAAASNo/11-VwwpuxbEqk8H-qqje_vIqNEkrqZG3gCLcB/s1600/Capture.PNG> where the indice I represent the Interface, n the number of iteration, f the fluid field and s the solid field. The h coefficient is calculated at each iteration with the CFD data. The fourier condition is the other name of the robin boundary condition.

This is very similar to the slip (Navier) boundary condition, see the example [1]. Essentially, just add a boundary integral such as that over Gamma_2 (dw_surface_dot, with the beta coefficient to 1) and then add a Neumann boundary condition (dw_surface_integrate term(?)). Tell me the exact form of the Robin condition if you need more help.

Hello,

I work on an aerothermal problem and i need to impose a robin boundary condition.

Do anyone know if this boundary condition is implemented in sfepy ?

Thanks,
