Why are my V-stops not allowing lateral movement during a Hydrotest load case in AutoPIPE ?
From AutoPIPE online help:
Hydrotest Non-linear Method
To enable hydrotest with gaps and friction, check the 'Non-linear' option for hydrotest load set in analysis sets dialog.
A non-linear static analysis cannot be performed on the hydrotest load case i.e. friction, support gaps and soil yielding are ignored.
