Problem:

The following is displayed when using AutoPIPE

* * * W A R N I N G - MODEL * * *
W2261-9: All stiffness values are zero for the following bilinear support(s).

Support ID Point Name
---------- ----------
A01 1 A01

Why and How to avoid it?

Solution:

This warning refers to the specified support(s) mentioned by the warning (ex. A01), all Stiffness values entered under the Ultimate Force Gap support are set to 0.00 (Zero). Since no stiffness value was entered, once the support restraint reaches the breakaway force (ex. 5000 N), the pipe will be free to move along the indicated support direction (ex. Global Y).

Note, when running a Non-Linear analysis, Spring rate value is ignored (see links below for more).

Avoidance

Confirm this is the correct modeling requirements for this support location and ignore the warning.

Or, update the Stiffness and phase values as needed.
