Hello,

Tank you for your reply. Here are more information about my case :

  • at the interface, i only specified "coupled wall" option.
  • i run my case as steady flow so there is no way to run a 'longer time'
  • i try to rise residuals and tested many models and many methods to calculate energy equation but nothing worked
  • concerning the mesh, i activated face meshing and used element size on every edge. I tested global size of 50µm, 25µm and 10µm but the results only changed about few K.

As suggested in the user guide you linked, i tried different value for under-relaxation factor of energy equation but it didnt solve my problem.

 

Thanks for your help,

Sincerely, best wishes for the new year,

Mickael
