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 Loads" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information.
Note: 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.
