Where does the formula for calculating the cylinder length when using Ansys to analyze head nozzles come from? (Including examples)

/clear /filn, E721A /title, Fatigue analysis of upper head of adsorber /units,si ! International unit system is used ! Parameter definition: Di=4400 ! Inner diameter of the device; tc=16 ! Wall thickness of the cylinder and head: Hc=5*nint(sqrt(Di/2*tc)/10)*10 ! Length of the cylinder in the model (including the height of the straight edges of the head); dn1=630 ! Outer diameter of connector 1; dn2=530 ! Outer diameter of connector 2; dn3=426 ! Outer diameter of connector 3 ...... Where do the calculation formulas in the red parts of the above command stream come from?
The local stress attenuation length is related to the diameter and thickness; this formula can be found in many books on stress analysis
Why are some formulas still expressed as hc=nint(4*sqrt(Di/2*t)/10)*10, while what I see is 2.5*sqrt(R*t)?
Replying to the person above: hc=nint(4*sqrt(Di/2*t)/10)*10 is used for rounding.
Its essence is to avoid the edge effects of the boundary conditions applied at the cross-section from affecting the stress distribution in the area being calculated.
