Hey there @apic !
For this project, I recommend that you use the standard meshing tool, as this geometry is quite complex, You’d have to extract the flow region, either by a boolean operation in your CAD software or via an enclosure operation in SimScale. You also have 2 sheet bodies in one of the hands of the cyclist, which could potentially be causing you issues right now.
Just not to leave you hanging in respect to y+, this is the (or one of the) causes for your issues with layers: all of them are being deleted, as you can see in the meshing log:
This quality parameter (min tet quality) can be turned OFF by inputting a big negative number (e.g. -1e30, which is the default setting). I believe you must have changed it by mistake to 1e30:
