The following message appears when running a model consistency check in AutoPIPe:
W726-12: Following Segment(s) not connected to other segments and has no anchors, Warning message in AutoPIPE
Why?
How to avoid?
With the model open in AutoPIPE choose Select> Connected segments:
This dialog will list all the segments into groups. Each of these groups are not connected to one another; essential disconnected segment groups.
This is OK modeling providing that each group:
1. Has at least one anchor or series of supports to restrain the pipe from excessive movement or rotation.
or
2. Is connected by Beam member to another group that is anchored or is sufficiently restrained.
If one or both of these are not met, then the model cannot be analyzed because the program will return the following:
---------------------------Error--------------------------- E801-1: FATAL ERROR : Unstable system. Need support at node xxxx Dir X ---------------------------OK ---------------------------
1. Assuming that the piping should be all one group of connected segments and this message appears. In order to find the disconnect use one or more of the following:
a. Tools> Coincident Node Checker, this option may need to be turned on by Tools> Model Options> Coincident Node Tolerance (0- no check)
b. From the "Select Connected Segment" dialog, the name of segments are listed, review Groups 2 and highlight segments in the model to narrow in on where the disconnect is located.
Once the disconnect has been located,
a. Insert an anchor
b. Connect one group to another using Connected anchor, or Piping component (review Correct a incorrectly modeled Tee / pipe), or Beam components as needed.
c. Insert more supports to sufficiently restrain the pipe in all 6 global axis directions
Note: This warning message will always appear if the one or more groups are connected by Beam elements. If this is the case, ignore the warning.
