Extended Airfoil

  I am currently running a simulation of an extended airfoil. However, I tried to use periodic boundary conditions in the spanwise direction of the airfoil in order to determine the periodic pressure gradient. Models: K omega-SST

  Check the mesh as the last image suggests the jump in cell size could be excessive. Why are you using pressure far field but then pushing flow through perpendicular to the boundary?

  I am using Pressure-far-field because of the application. yes, i also observed the mesh is not sufficient and I have to re-mesh.
  
  Thanks Rwoolho

  I don't understand what you mean by pushing flow perpendicular to the boundary?

  Oops, meant perpendicular to the periodic boundary.

  I changed my Mesh and the errors are no more. However, is there any limitation of using periodic boundary conditions in Fluent icing? Because I successfully run the airflow solver but when I tried to run the droplet solver it's constantly giving me error of 999999 mpt_accept failed.

  Possibly, I've answered in the other thread. I'll lock this one seeing as the problem is resolved.
