Can all dynamic analysis (ex. Response Spectrum, time history, Harmonic, etc..) be performed on underwater piping correctly while using AutoPIPE?
Assuming the pipe is correctly supported by soil properties, select a range of piping where concrete mattress will be laid across, select Insert> Distributed load..> suggest "Load case to combine with " = GR, enter correct value of weight in vertical down direction, and press OK button to apply.Or, add additional weight using insulation thickness and density
Note: To model stiffness of concrete mattresses restraining the pipe. Two approaches are:
A. Insert soil over this area with equivalent stiffness to match rigidity of mattressesB. Insert V-stops with high friction e.g. much greater than 1.0
