Is there a method to perform a Hydrotest as a non-linear analysis?
Please see the following AutoPIPE help section:
Help > Contents> Search Tab> enter "Hydrotest Non-linear Method" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information.
Note:
1. use Non-linear analysis method of calculating stress in the model if the hydrotest load-case is to be analyzed while considering support Gaps, modeled Friction, and/or Soil properties. Otherwise, use Linear analysis method if gaps, friction, and /or soil settings are to be ignored during the stress analysis.
2. However, know that AutoPIPE will still automatically converts all designed and undesigned spring and constant hangers to a rigid hanger (V-stop) to simulate locked hangers regardless of Linear / Non-linear selection. No option will be added to the program for unlocking a spring during a hydrotest. Suggest to not use a hydrotest load case, instead configure a new P/T case to represent the Hydrotest load and run as a normal non-linear analysis (897484).
