Strange lines on the control volume in fluent
 

I am simulating a 3d profile on fluent, when the mesh is uploaded on fluent it appears an strange line from the extrados to the intrados of the wing.

The pictures shows the line in a 2d plane, it occurs on the whole control volume 3d.

Do you know what does it means? maybe a bad meshing?

I have over 3 million elements, but im getting bad results, what models do you use in that cases ?

Many thanks in advance!

I think you are running a parallel simulation and the "line" you see is the partitioning line, so no problem.
Do a mesh check to see if everything is ok.

Thanks Daniele!

One more think, I suppose the use of parallel simulation (when i choose the processes on fluent) is to put how many the cores my computers uses, so it goes faster but does not affect on the results isn't it?

Many thanks!!

Yes, the number of cores doesn't influence results; for other problems, if any, check carefully your boundary conditions and your mesh.
