Can you proof equation on my figure. Because when I conduct procedure which is placed in your comment or in altair help, i couldnt find same value with hypermesh 2021.1 output. I want to use that ratio in mitigation condition for bolted joint failure due to the that reason, i should know exact idea background of ratio.

Jason i know, but please inspect my example which is given previous post. X and Y in plane direction

Up side sqrt(13.2418^2+6.22841)=14.63346

Down side sqrt(14.118^2+3.33752^2)=14.507

Internal Side sqrt(1.42091^2+10.581^2) =10.675

Dls_R = min(Up/internal,down/internal)

But I couldnt find hypermesh output 0.485868.
