Hi everyone

I'm having some problems with my simulation. What i'm doing is a delta wing through wind at -5ºC. What I want to do is to study de vortex geometry formed at the leeward side of the delta wing. For that i'm usin RANS, pisoFoam, k-e model. With a y+ value of 30, so i'm usin the wallfunctions. The mesh is a cube with the delta wing positioned near the front face (inlet, named "entrada") and two conic volumes that melt with the back (outlet, named "salida"), the contour has to be open space like if the delta wing were levitating in the air, so non wall function is applied for the contour named "contorno" and i give them the same properties as the inlet ("entrada"). Wall functions are applied over the delta wing for epsilon, k, and nut.

i'm attaching the 0, the contstant and the system folder without the mesh because it has over 6e6 cells. The quality is ok, gmsh and checkMesh said so.

Soon I'll attach some pictures of the geometry.

MY QUESTION IS: What am I doing wrong with the BC or some of the other files in constant and system folder or is just a mesh problem?

Thank you very much.

PD: If some one has any k-e simulation files, would you send them to me please?
