Hi

There is simple piping system that was modelled in CII 2016, later it had to be re-modelled in CII 2013 as the end user did not have the latest version.

CII comes up with a different set of results from both versions.

For example, we have W+P1, WNC and W load cases. In the Restraint Summary, numbers from WNC and W exactly match between both versions, however for the W+P1 numbers from CII 2016 do not match CII 2013.

We have checked the input to ensure P1, Bourdon activation in both the versions are identical, also did normal checks a user would do.

Please advise if there is something that has been missed out that causes the discrepancy.

Felix
