Problem:

The following appears in the model consistency check report:

 * * * W A R N I N G - MODEL * * *
W2164-159:The value of "Stiffness" or "Spring Rate" is zero for following supports.

How to avoid it and fix it?

Solution:

This would just be a warning to alert the user that the indicated support(s) listed have a Spring stiffness value = 0.00. Another words there would be no restraining support force in the bearing direction of a particular type of support; as if the support was not there regardless of other support settings. 

Example:

Given the following guide support settings:  

Regardless of Gap settings, Friction value, there would be no support force on the pipe in the bearing direction (i.e. vertical & perpendicular to pipe).

Avoidance, enter a Stiffness value greater than 0.00
