[Inflate boundary layer - Refinement] - Critical problem

Hi @Get_Barried!

  1. I have followed your recommendations, using layer refinements with 1.2 for expansion rate and # layers = 6, for different values of the "minimum overall layer thickness”. These are the meshes:
    -V2.RW_C_0.00001_NoFEAT_NoMin_6_1.2 .> "minimum overall layer thickness” as in previous attempts (0.00001 car, 0.0001 floor)
    -V2.RW_C_0.00001_NoFEAT_NoMin_6_1.2_0.01 -> "minimum overall layer thickness” up to 0.01 here

  2. Anyway I suspect that the lower the "minimum overall layer thickness”, the easier it should be for the layers to show up, since I consider it as a threshold below which layers are not created (i.e. if it is zero, then the layers will be created no matter how small they have been defined, isn’t it?

  3. Another guess: may the exporting quality of the geometry be influencing the creation of the layers? I have just realized that the quality in which the .STL were being exported is so low that edges can be observed easily even in a surface which was supposed to feature a high degree of continuity.

  4. All the meshes of the project present have layer refinements defined, but the study focused on this kind of refinement starts from mesh V2.0 onwards. From V2.0 up to V2.7 the base geometry is FUC3M17. The ones which feature ‘RW’ in the name are based on the ‘2017RW’ geometry. In particular, mesh V2.6 was supposed to be my final configuration -until I discovered the inflation layer problem-, so it is somthing like the reference one.
