We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,
Looking at the screenshot, the tornillo_d8_L25.3\OuterThread geometry is a surface type germetry. Since the analysis is 3D, it is asking for the thickness of the shell elements that will be created for this geometry.
I think you may have to revisit the CAD model and see if this arrangement is exactly what you want.

You can apply pretension to a bolt without nut. Make sure that the threaded part of the bolt has proper connections with the clamp.

I hope this helps.

Regards,
