Problem:

AutoPIPE allows the creation of two hydrotest static analysis sets by pressing on the Hydrotest button and selecting "New Hydrotest loadset" setting multiple times.

However, when two hydrotest sets have been created, selecting Hydrotest>Hydrotest Load Properties and changing the pressure and/or temperature causes the changes to be applied to both sets, not just the one selected.  The effect is only one set of Hydrotest conditions can be applied.

How to apply more than one hydro-test analysis sets with different settings to an AutoPIPE model? 

Solution:

Correct, AutoPIPE allows the creation of two hydrotest static analysis sets. Pressing the Hydrotest button and selecting "New Hydrotest loadset" setting a 3rd time will display the following:

---------------------------
Bentley AutoPIPE
---------------------------
Only upto two hydrotest loadsets are allowed in the model.
---------------------------
OK
---------------------------

Also correct that the Hydrotest Load Properties remain the same between the 2 hydro-test analysis sets, this is by design. Making changes to the Hydrotest load properties will display the following message:

---------------------------
Bentley AutoPIPE
---------------------------
All hydrotest loadcases have been updated.
---------------------------
OK
---------------------------

However the user is able to change the following settings per each analysis sets as desired:

• Pressure Stiffness
• Hot Modulus
• Pressure Extension
• Fluid Density Factor
• Non-Linear
• Cut-short
• Ignore friction GR

A new enhancement has been logged to allow different Hydro-test Load Properties per analysis set (TFS-439172)
