Hi,

In order to calculate yPlus I am using the code I upload as an attached file. The equation that you can find in the file yPlus.C uses a variable "d", i.e. the distance to the wall. I had a look at the values of this d. I expected them to be the same all over the airfoil I am computing (since I am using a mesh with constant 1st cell height of 2.75e-5). To be sure that this is constant after having converted it to OF, I checked that in a post processor and this 1st cell height is constant, so there are no "conversion issues"). :S

What I get is that they oscillates between 9e-6 and 1.3e-05. I don´t like this because the value of the computed yPlus then is not perfect.

Can you tell me anything about this?

Thanks,

Regards,

José


P.D.: BTW, if you want to know anything else about this yPlus tool I am using, the one I have uploaded, you can co to the thread, post number 5.

Post #18 is my guess on what may be happening.
