&lt;p&gt;As you may already know, at this time, Dec 2022, AutoPIPE&amp;#39;s linear analysis analyzes all of the load cases all at the same time. Another words, no one load cases depends on the others. However, if the analysis is to consider features like Gaps, friction, and soil then the analysis would need to run a Non-linear analysis. This type of analysis requires the load cases to be analyzed in a sequence. Gravity is always the first load cases applied, followed by the remaining load cases of the analysis in any order.&lt;/p&gt;
&lt;p&gt;Please note that ADL Pipe was assimilated into &lt;span&gt;AutoPIPE V8i&amp;nbsp;&lt;/span&gt;09.01.01.02, Nov. 2008. Since then AutoPIPE has undergone many, many, many, audits and passed most&amp;nbsp; with no findings. Regardless, if you like to benchmark AutoPIPE with ADL Pipe by all means do so. Suggest that you compare results using a Linear analysis.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;In the end, if you find a discrepancy please provide the information &lt;a href="/products/pipe_stress_analysis/w/pipe_stress_analysis__wiki/7715/--technical-support---autopipe"&gt;&lt;strong&gt;here&lt;/strong&gt; &lt;/a&gt;(results are being challenged) proving where/how AutoPIPE&amp;#39;s current version is wrong.&amp;nbsp;&lt;/p&gt;
