Why Salome does not supress face properly in this case

Hello 

I have a NACA 0015 airfoil with a rounded trailing edge. When I try to suppress the airfoil face it does not suppress the trailing edge face properly instead it suppresses it as shown in the attached image.

Can you please tell me how to fix the problem?

Hi

It seems to be just a visualization effect. You can improve the image by decreasing Deflection Coefficient: select your geometry, in a contextual menu in the Viewer select Deflection Coefficient and set it = 1e-6.

Hi Mr. Michael, thank you for your reply

After decreasing the deflection factor to 1e-6 that does not solve the problem too.

See attached image

You made that image after pressing OK in Deflection Coefficient dialog?

Here is a link to the Salome study:

P.S: I am using Salome 8.3 on windows 10. 

Hi Michael 

Yes of course I made that image after pressing OK. I reopened it just to show you that the deflection factor is decreased but with no effect.

Hello

I think that problem is due to the small radius of the trailing edge (R = 1mm). So I scaled the geometry with a factor of 10. The problem is solved as shown in the attached image.

I think that I can also transform back to the original geometry by scaling it by a factor of 0.1
