This is a Multi-Thickness Shell. I can understand 8mm. What is 20mm?
I do not see url to your reference.
This issue has nothing to do with k-factor.
If your part is supposed to be 20mm - it is already too thin.
It removes the Shell from the large flange. If you turn on show preview, as in the image below, & increase the thickness setting from 8mm to 20mm you will see the Shell slowly get smaller & then disappear from the flange.
8 is OK. Which is 20?
Effectively there is no 20mm that can be measured. If you do what I said in the previous post you will see that the Shell thickness increases until it is greater than the thickness of the flange, then the remaining Shell surfaces combine with Face<1>
So that 20mm is like K-factor in SW.
Does it matter if we give 17mm instead of 20mm?

Try it. Change to 17mm. What do you observe?
No trial and error needed.
Please see the bottom post.
What you saying is it is part thickness determine Multi-Thickness Shell value (20 or 17)?
So, select the face in the multi-thickness settings box and it should highlight. I'm guessing it's the angled face on the back of the part.
I'm on SW2015 so I cannot open your future version file.
If you uncheck multi-thickness, the skin of the model will be (default) 8mm everywhere
with this option checked, you can manually pick the face and enter the thickness
I tried with your explanation I can realize that 20mm is preventing the face<1> getting shelled. Even 17mm is not shelling but 16 mm is slightly shelling. I do not know how this number can be decided in real world other than trial & error.
Not really, since the thickness of the flange is 17mm so you can try any number equal or greater than 17mm to avoid the channel of 8mm
