Error: Map value does not exist
 

Dear All,

I am trying to simulate an airfoil at 4deg AoA. After I made the mesh and ran the simulation, I want to include a y-plus and Cp plot. I did this multiple times for different meshes, but I am getting the following error using this particular one:

ERROR Map value does not exist for domain vertices 36434 and 36435.

This happens when I make a polyline intersecting the airfoil and a plane in the middle of the domain,parallel to the flow. I do not get this error when making a circle with radius 0.5m, which perfectly encircles the airfoil.

How can I fix this? Is it possible to identify where vertices 36434 and 36435 are located?

Thanks in advance,
Tim
