Hi Everyone, I’m trying to create the Y+ layers over the bounding box in Ymin Direction. So here’s my approach that I followed So I’ve created a Bounding box where Xmin is -15 and Xmax = 15, Ymin 0 and Ymax=0.5 (All dimensions are in m) I’ve calculated the wall distance by considering the bound…

Hi @sumedhsurve ! Tagging our PowerUsers @Get_Barried & @DaleKramer here who might help you out with that. Best, Jousef

I am not totally sure about what results you expect but I copied your project and made some layers for you. Here is my copy with layers . I will leave that for a few days and then erase the project. First, I assume you want an external mesh if you are layering the Bounding Box. With that assumpti…

Hi @DaleKramer , Thank you very much I’m trying to access that project which you created, but iIm getting errors.

Sorry, forgot to make it public, should work now.

Oh, and I forgot to mention that since you have left ‘Use relative size for layers?’ at the default value of True, you will not obtain your desired final layer thickness of 0.01479m. The final layer thickness will be a ratio of the thickness of the ‘further out’ cell next to the thickest layer th…

@DaleKramer @jousefm First of all sorry for the late response, some important stuff came across. Just to give you more information about this project so Here I was trying to create the layers over the surface of that trapezoidal shape. Few things that I’ve noticed Its bit difficult to create …

[image] sumedhsurve: A) How should I create the layers on that Trapezoidal Section with STL surface or be more precise by using bounding box layer addition method? (Again I want the layers to be generated over the horizontal surface of that trapezoidal Section so I can see how the roughness beh…

@DaleKramer Can you tell me how did you estimate this value under which Y+ it comes.

Do you mean how can I ensure that the layers made using a ratio of, say 0.3, in a ‘relative’ layering scenario will match my desired Y+ value ?

@DaleKramer , I mean I can still calculate Y+for this 0.3 as we have all the values there. My Question is specific how did you know this thickness will work for this case. What is the logic behind this ?

Use of Bounding Box Layer , Y+ layer, boundary layer

Using SimScale

You are using the wrong refinement to add layers to a geometry face. Use this:
