I would like to ask fellow users: when using WRC107, on the vessel data page, if I select \"Include pressure stress indices (Div.2)\\", the calculation results show as \"failed\"； Before clicking, the calculation result was passed. What is the reason? ； I’m a beginner; I hope experienced users can give me some guidance.

As far as I know, WRC107 did not take into account the effect of internal pressure when checking the local stresses in the shell; however, this is unreasonable in the design of pressure vessels. Therefore, when checking nozzles, it is necessary to select the option to include pressure stress indices (Section 2). It is recommended that you check whether the pressure inside the container has been set correctly.

Are you using PVELite for the calculations?
