Boiler Header stress calculation problem

The header in the boiler always has more than10 tubes connected to it at one point,but now the autopipe just can create one node at one node.So how to creat more than10 tubes at one node?Or how to calculate the Panel stress for the boiler.

  • Greetings, 

    Are you using AutoPIPE or AutoPIPE Vessel?

  • I am using  AutoPipe.Is there a method to solve it?

  • Greeting, nothing is stopping you from modeling multiple pipe segments all connected to the same node point (ex. A00):

    Suggest that you specify a user SIF at the junction point (ex. a00).

    Question: how to connect all pipes at a signal node point/?

    Answer: same as when connecting 2 segments to form a tee, on the next run dialog specify the "Name of Node" = name of existing node point on other segment, press the tab button on the keyboard, and press OK to close the dialog. The junction will be automatically connected.

  • Hi mike:
        Thanks for you quick reply.
        I am a new user for  the AutoPipe.  So I know it a little. I have two questions as below:
        1:What is the user SIF?  Is it a coefficient? How to specify  it ,I see there are so many option for it, which one should be choose? 

    2: I do not specify a user SIF, I  creat a  node A139 and then  try to creat all the followed node  connect to it  by change the  origin point, but they do not connect to A139,they still connect by sequence.
    3:The tube for the boiler header will be a circle as followed picture, is the available?
